Description

A RECYCLE RATE ASSESSMENT METHOD OF A VEHICLE}

The present invention relates to a method for evaluating the recyclability of a vehicle to evaluate the recyclability at the design stage in developing and manufacturing a vehicle.

As the destruction of the environment caused by vehicles has become a serious international issue, the Junction of the Junctions, which was finalized in the European Union in June 2000, requires annual recycling targets, mandatory retirement of our vehicles, the disposal of vehicles and the environment of recycling processes. The annual recycling target is regulated at 85% in 2006 and 95% in 2015.

As a result, the recycling target has been determined to bear the cost of the recycling target to automakers from July 2002 in connection with the mandatory collection of vehicles.

The legislation is expected to cost approximately 13 billion euros ($ 11.7 billion) for the entire automaker, and requires an objective algorithm that will reflect the tools and tools for evaluating recycling at the design stage. It is expected that there is a problem of not being able to adequately cope with the trade barriers of the new environment and the expenditure of huge foreign currency because there is no developed matter.

The present invention has been invented to solve the above problems, the object of which is to develop and manufacture a vehicle in the manufacturer of the recyclability evaluation data for all parts constituting the vehicle (material, fastening, dismantling structure data, etc.) Calculate the recycling rate and the disassembly order, the expected dismantling time, the material classification constituting the vehicle weight and weight, and the composition ratio of the weight by material. The results of the evaluation, including the reflection design of the recycling technology through the derivation of materials, couplings, and structural factors for improving the recycling of each part, are included. This results in the development of vehicles with excellent recycling.

In addition, through the dismantling time of the vehicle to predict the cost to be processed when the vehicle is to propose a guideline for cost reduction.

The present invention for realizing the above object comprises the steps of collecting and disassembly evaluation data for each vehicle in the database; Inputting vehicle type and specification information and vehicle dismantling data for the dismantling evaluation; Calculating and analyzing recycling characteristics by reading evaluation data from a database according to the input information; Determining whether the component calculated and analyzed in the process is an assembly; Calculating a recycling property from the evaluated result list in the case of a part part and storing the result in a result database; In the case of the assembly, the evaluation data is read and analyzed according to the disassembly information of the assembly component parts, and in the case of the part parts, the recycling property is calculated from the evaluated result list and stored in the result database.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As can be seen in FIG. 1, the apparatus for evaluating recycling of vehicles according to the present invention includes a basic database 10 in which basic information collected for the evaluation of recycling of vehicles is set, and a recycling evaluation for the corresponding vehicle model. A condition input device 20 for inputting general conditions for the vehicle, an evaluation device 30 for performing a recyclability evaluation on the vehicle based on the basic information according to the input condition, and the recyclability evaluation data A result storage database 40 for storing and an output device 50 for outputting the evaluated recycling data in the form of a document, a screen, and other forms.

The vehicle structure requires the need to be separated in a special order, ie in the reverse order of the assembly order.

For example, the dashboard must be removed before the air conditioning system can be separated, and additional parts must be dismantled to ensure that many of these parts are in a single material category allowing for material recycling.

Even the same product may have different costs depending on the order of dismantling. Especially, since the economics of dismantling work can be improved by disassembling parts with high added value first, the dismantling structure of the product has a great influence on the calculation of dismantling cost. .

With reference to Figure 2 look at the posterior relationship of dismantling between parts as follows.

As can be seen in the figure, the parts in the first stage of disassembly can be removed without any preliminary separation and are not affected by the disassembly order.

However, parts after the dismantling stage 2 need some preliminary work, which means the removal of other parts, and it takes a lot of time for the dismantling work and difficult dismantling process. You can see that it takes more time, and the work gets more complicated.

Therefore, in order to determine the decommissioning order and derive the expected decommissioning time for economic decommissioning operation and the calculation and achievement of the recycling rate, the decommissioning evaluation data is first collected and analyzed.

Most automobiles, which consist of more than 20,000 parts, have a clear order of dismantling, and some parts can be removed without a fixed order.

Therefore, in order to systematically perform the dismantling of a large number of parts, the dismantling process is classified after setting up dismantling processes such as liquid, shell, internal, engine, and exhaust system.

In setting up the above-mentioned dismantling process, in consideration of the efficiency of dismantling operation, the process of disassembly is selected and the disintegration target in each process is selected.

In addition, the disassembly order step 1 is a vehicle dismantling step of separating the assembly or parts to be dismantled from the vehicle in the order according to the dismantling diagram of the vehicle, and the evaluation data is composed of a combination type and number, dismantling time, tool used, weight, material, etc. do.

In addition, in order to evaluate the degree of disassembly by the connection structure for each assembly, for example, a vehicle dismantling structure diagram of the front bumper as shown in FIG. 5 is prepared, and a dismantling step of parts to be evaluated for structural evaluation, parts to be removed in advance, and Collect data such as disassembly order.

When the vehicle dismantling data is collected as described above, the data of part dismantling, which separates the assembly parts into a single material, are performed in the same manner as in the case of dismantling the vehicle, to collect all data for recyclability evaluation and to the basic database 10. Set it.

The above data collection is summarized in Table 1 below.

step division Contents Remarks I Dismantling Process ■ Decomposition Target (Assembly) Process Arrangement Improved dismantling efficiency Ⅱ Vehicle dismantling Assembly disassembly from car body: vehicle demolition diagram Data grasp between assemblies: form, quantity, material, weight, tool used, time Ⅲ Parts dismantling Single material separation from assembly: part dismantling Assembly component data identification: form, quantity, material, weight, tool used, time

In the vehicle dismantling step of Table 1, for example, the evaluation data collected in dismantling of the front bumper becomes as shown in FIG. 6.

When the basic data of all parts of the vehicle is collected and set in the basic database 10 through the above-described process, the process of performing the recyclability evaluation in the design stage is performed based on the collected basic evaluation data. A description with reference to FIG. 3 is as follows.

First, after selecting the vehicle model for the evaluation of the recyclability through the condition input device 10, and then select the specification for the vehicle model, and set the format of the new file for continuous use (S100), the vehicle for the selected vehicle model and specification Enter the dismantling data (S200).

At this time, the vehicle dismantling data to be input is divided into vehicle dismantling data data and parts dismantling data data.

As described above, when the dismantling data is inputted, data about the fastening elements between parts or assemblies is inputted, and when the input of the dismantling data is finished, the dismantled order between parts is entered.

When the conditions for evaluating vehicle recyclability are input as described above, a processor (not shown) in the evaluation apparatus 30 includes a material base database containing information on materials and a base information on fastening and tools. After reading the information on the selected vehicle model and specification from the database (A) consisting of the decommissioning analysis for the input data (S200).

Determining whether the form of the dismantled parts through the dismantling analysis is the assembly (S400), if the assembly again performs a second dismantling analysis on the material, fastening, structure, etc. for the assembly parts (S500) To return.

Input to the data for the dismantling analysis of the corresponding parts through the return to the S300 is repeatedly performed in the same process as described above.

If the disassembly result obtained through the above-described repetition process is a part, a recycling evaluation list of input data is calculated (S600), and the calculated evaluation result is stored in the result database (B) (S700).

In addition, according to the operator's selection, the result is output to the screen or paper through the output device 50 in the form of letters or numeric graphics.

Subsequently, when the inquiry of the recycling evaluation list stored in the file format is requested, the corresponding file stored in the result database B is read and the information on the corresponding file list is output (S800).

As shown in FIG. 4, the calculation and analysis of the input data for the dismantling analysis of the S300 is carried out in the design improvement evaluation part of the pre-evaluation concept that can be evaluated from the design data at the time of development for the vehicle, and at the time of discontinuance after the vehicle development. The analysis is divided into the RAC rate evaluation part of the post evaluation concept for predicting the recycle usage and the recycle rate.

In the case of the design improvement evaluation part described above, when the disassembly evaluation (①) for selecting the conditions of the vehicle disassembly and parts disassembly is set, the degree of connection between the parts, the number of components and the disassembly order on the structural side are determined by using the dismantling structure diagram. Structural (②) analysis is used to quantitatively evaluate the effects, and binding (③) analysis is used to quantitatively evaluate the effect of the fastening elements using the fastening elements and dismantling time used.

As described above, when the analysis evaluation of the structurality (②) and the binding property (③) calculated in each dismantling step is performed, the disassembly (④) is comprehensively analyzed.

Subsequently, if the material used for the part goes through an analysis step of materiality (⑤) for evaluating whether the material is easy to recycle, the evaluation part is finally made using the analysis results of dismantling property (④) and materiality (⑤). Recyclability (⑥) that quantitatively evaluates the degree of easy recycling is calculated.

The redesign information that can improve the recyclability through the improvement of the inhibitory influencer based on the evaluation component is derived through the analysis of the recycleability score calculated in this way (⑦). (8).

Meanwhile, using the materials used after the analysis of the recyclability, the current use of the recycle, the recycling possibility (1, 2), thermal recycling, waste, hazardous substances, etc. are determined (⑨), and using the determined recycling use, the evaluation vehicle A post-evaluation process is performed to calculate what is the probability of recycling.

In performing the above-mentioned recycling evaluation, it is classified into the collection of basic data related to dismantling, input of dismantling data, and preparation of evaluation result list.

In the above-mentioned collection of release-related basic data collects data on the coupling element that is joining the part and the material for the component and the component and the tool to separate the coupling element, the collection of data for the coupling element The part used in the calculation is used to predict the time taken to remove the coupling element of the part. The part used in the calculation is determined by the coupling index of the coupling elements.

The above coupling index means the time taken to separate one coupling type of a component into an optimal general tool.

In addition, the collection of data on the material element is a part for inputting information on the material of the separated part and the material of the coupling element, and the information display of the material on the part is divided into recyclable and waste materials.

First of all, metal, plastic, rubber, liquids and other materials are largely classified into material groups, and the major categories of materials are classified into non-ferrous, iron, thermoplastic, thermosetting, antifreeze, refrigerant, etc. in detail step by step. It is a market price analysis of recyclables so that the classification of material name, which is a unique name of the material, the material notation, which is a symbol of material, and the disassembly of the vehicle can be determined through economic analysis after dismantling the vehicle. .

The analysis of the market price of the recycled materials is not available at present because there is no recycling distribution market for materials other than scrap metal, but it is a high utilization item when a recycling distribution market is formed in the future.

In addition, analysis of the hazards used to determine disposal problems (incineration, landfill, and specific waste) for shredder after dismantling and calculation of calorific value to determine whether the material from which the dismantled material is thermally available can be performed.

The collection of data for the tool above correlates with the coupling element as a part having information about the tool used to remove the coupling element of the part.

This includes tool preparation time to prepare the tool to remove the coupling element and tool replacement time to replace an existing tool with another tool to remove other coupling elements.

This time is a time value used to determine the additional dismantling time in addition to the dismantling time of the assembly using the use coupling element and the influence of the dismantling work such as tools.

First, it is divided into tool preparation time and tool change time, which is the time taken by the operator to prepare the tool for the coupling connection element. In case of hand, it is assumed that there is no tool preparation and replacement time and the time value is 0. For the rest of the tools, the tool used for disassembly is considered to be within the working radius, and all time values are considered to be 2 seconds.

In addition, in the case of inputting the dismantling data, input data on the assembly and the single part for the part to be evaluated, and inputs on the coupling element between the assembly and the single part to evaluate the overall bondability, structure, and dismantling. Enter the information as well.

In addition, in order to create a dismantling structure diagram for the product to be evaluated, input and forth relationships between dismantled parts are also input.

Input of dismantling data above is input of information about separated assembly and single part firstly. If the corresponding part is assembly in the input for the next step, the result of dismantling in the next step is part part, that is, the material is a single material. Instead of inputting the dismantling information for the lower level, if the dismantling result is an assembly, the information of the disassembled parts is inputted by separating the single material parts.

In addition, when dismantling a part, it must be dismantled before this part to determine the predecessor that determines the order of work that can be separated.

The design improvement evaluation is the evaluation result part of each of the combined, structural, dismantling, materiality, and recycleability scores for the input and dismantling of the vehicle. The parts to be evaluated are the exterior and interior parts. do.

In the foreign waste disposal regulations, liquids are pre-removed materials to prevent soil pollution, and engine-exhaust system parts are recycled at the current level because they use used parts and account for 75% of the current vehicle recycling rate.

First of all, in the case of structurality, the ease of disassembly is expressed in the structural aspect between components, and the total structurality is calculated as the sum of vehicle structurality and component structurality.

Vehicle structurality is the sum of the dismantling stage and the number of preceding works when dismantling the vehicle, and component structurality is the sum of the dismantling stage and the number of components at the time of dismantling of parts, minus a predetermined score for parts that can no longer be dismantled or are complex such as electric board .

The total structural weighting was given to the vehicle structural and component structural scores, respectively, for the reason that the dismantled parts must be of a single material in order to be able to recycle.

As a result of the decommissioning evaluation, on average, the ratio of single materials in vehicle disassembly and parts disassembly was about 20%: 80%.

The binding score is determined by the score conversion table of the dismantling time as a score for the time taken to remove the binding form (multiplied by the coupling index).

The total bond score, like structural features, is calculated as the sum of the vehicle and parts, which has an important function of calculating the expected dismantling time.

The material property represents the degree of easy recycling for a single material obtained after disassembly. First, the thermal aging stability for evaluating the degree of degradation of physical properties caused by heat and other factors during regeneration processing and the ease of processing for regeneration are evaluated. Contamination degree that distinguishes the intrinsic material properties and the degree to which a single material part is contaminated by oil and grease affects the physical properties, whether or not the coating is considered in consideration of the influence on the material properties by surface coating, and the material properties by plating It is expressed by the reproducibility of individual parts which are quantitatively considered in consideration of the degree of plating in consideration of the degree of giving, whether or not the material is identified by material marking.

Through the dismantling and materiality scores calculated as described above, the degree of recycling of parts is estimated.

Recyclability ratings are calculated by applying the absolute evaluation method of calculating the percentage between the ideal value and the lowest value to calculate the recycling property rating through Equation 1 below.

The value for the recycling evaluation result calculated through the above process is shown graphically as shown in FIG. 7.

At this time, target average values such as vehicle bondability, vehicle structure, component bondability, component structure, vehicle disassembly, component disassembly, material property, total bondability, total structural property, total dismantling property, and recyclability are compared for each evaluation part. Can be.

In the comparison, a redesign guideline is performed on a graph item whose recycle evaluation result is lower than a target mean value.

The performance of the redesign guidelines derives the recycle inhibitors for items such as vehicle and component coupling, vehicle and component structurality, and materiality which are lower than the target average value in the result of the recycling evaluation.

By deriving the inhibitory factor as described above, the recyclability can be improved by promoting the redesign to improve the inhibitory factor of the evaluation component.

As described above, the present invention corresponds to the recycling laws by analyzing the recycling characteristics in the design stage of the vehicle and reflecting them in the redesign, and provides a guideline for predicting and reducing the costs to be handled at the time of decommissioning through the dismantling time. .
