Description

Technical Field [0001] The present invention relates to a product design method using an integrated design framework and data filtering,

The present invention relates to a product design method, and more particularly, to a product design method in which a specification described in a data sheet of a product is input from a predetermined manufacturer, a product design is requested, and a vast amount of data searched is filtered through a product type distinction, The present invention relates to an integrated design framework that can provide design information for a product to a predetermined company, and a product design method using data filtering.

In order for Korea's shipbuilding and marine industry to maintain its No. 1 position in the world, it is essential to improve productivity by developing high-efficiency production technology.

As one of these efforts, the shipbuilding marine production simulation field has emerged and a simulation system specialized for the shipbuilding marine industry is required.

In order to integrate in consideration of scalability, we have developed a framework program for the production simulation of shipbuilding marine and based on this, studies are being conducted to develop a friendly application system for users in the shipbuilding marine industry in Korea.

In order to develop such framework programs and application systems, it is necessary to first derive and analyze the requirements of the field personnel of the shipbuilding industry, which is the end user, and to develop the system based on these requirements.

However, due to the special nature of shipbuilding marine industry, which is called engineering to order, there is a limitation in directly applying simulation systems and tools applied to mass production industries such as machinery, automobile and airline (Make to stock, order) Industry-specific production simulation technology.

From this point of view, existing Korean large marine related companies have developed various production simulation programs.

These programs are usually developed by the needs and needs of demand departments, and they are helping to improve productivity.

However, conventional shipbuilding marine production simulations are being developed individually and locally by various marine related companies, and are being developed / operated with different structures.

These disadvantages are in terms of module recycling and reusability due to individual development and different structures.

On the other hand, the feedback loop design technology combines the simulation-based optimum design technique with the appropriate design technique based on the commercial product database to derive the optimum design result through multidisciplinary analysis, (CAE) based verification after determining appropriate commercial products.

This technology forms a feedback loop structure that reflects all the information of the whole process to the design, such as commercial product design verification result and optimum design result.

As shown in FIG. 2, by using the conventional feedback loop designing technique, the effective thrust is 29038 [kgf], the buckling safety factor is 1.5, and the minimum rod inner diameter is 77 [mm] As a result, data on 207 large selection candidates were searched.

However, among the retrieved data, there are specifications other than the numerical specification of the product specification. Therefore, there has been a need for a technique capable of filtering an enormous amount of data in order to select an optimized specification product.

The operation of the integrated design framework and the product design method using data filtering according to an embodiment of the present invention will be described with reference to FIGS. 3 to 8 as follows.

In general, the design improvement method for the offshore plant equipment is carried out on the characteristics of the offshore plant equipment and the mathematical model for each part is obtained based on the obtained data. Simulate the characteristics of the equipment of the whole offshore plant.

At this time, in order to analyze the characteristics of equipments of offshore plant, it should be designed to minimize the instability factors.

Accordingly, the present invention determines the cause of instability, which is a problem in analyzing the characteristics of the equipment of the offshore plant, by using the following algorithm, and selects a suitable equipment product.

When designing a product of the offshore plant is requested from a predetermined company (S110), the design and analysis modeling is formulated (S120), and the analysis model is created in a file form (S130).

At this time, general specifications about the product type, usage method, installation place, and the like are inputted through a graphical user interface (GUI) that the requester can input when requesting the product design.

The input information is temporarily stored and then used to filter data when a proper product is selected from the product DB in a DB-based appropriate design stage.

Here, since the items of the information providing graphic user interface may be different depending on the product, it is necessary to develop a customized item according to the product.

For example, as shown in Fig. 5, a design for an optimal hydraulic cylinder to provide a thrust F, which is a compression force applied to both sides of a Moonpool, from a predetermined marine related company .

6, the supporting force of the structure is changed by the thrust F applied to both sides, and the operating safety of the structure is improved by the supporting force. Is determined, the thrust F is usually applied by using the thrust of the hydraulic cylinder.

In addition, the hydraulic cylinder for offshore plant is a marine plant equipment that requires high reliability because it operates from time to time in response to the change of sea level due to waves, and it requires complex technology such as high durability due to salt contained in seawater.

At this time, the concept of the axiomatic design method is introduced as an approach to sufficiently reflect the requirements of a predetermined company that requests a product design, and the requirements can be automatically reflected.

The axiomatic design method of the present invention means that the design process is divided into a series of goals and methods: customer requirements, functional requirements, design parameters, and process variables. It is a design methodology that evaluates each of the design matrices by proceeding to the selection process of the branch domains and mapping process accordingly.

In other words, in order to select the most suitable product to be used at a predetermined company site, it is very important to collect and analyze the requirements of a predetermined site person, It is important.

Based on these requirements, the concept of process simulation can be established and a more practical system structure can be established.

In this process, a process of specifying and specifying the requirements of a predetermined company as an end user is performed. In the requirement definition stage, based on the interviews with a site official of a predetermined company and the related minutes, Identify customer needs with definition / analysis.

In the analysis and design process, it is possible to grasp more specifically through techniques such as Use Case, and to analyze and understand the operational concept of the end user to be developed by the simulation application system to be developed through the requirements of the customer.

In order to construct the R & D strategy, the development priority in the viewpoint of the user (customer) is considered, and the requirements to be developed prior to the development of the simulation framework program and the application system are specified.

In addition, it is possible to introduce a process of analyzing functional requirements in order to satisfy the customer requirements represented by the field personnel of a predetermined company derived / analyzed. In this process, And defines the functional requirements as an implementation function to meet the requirements.

A functional requirement is a functional specification or specification of relatively unspecified customer requirements.

In general, customer requirements are a specification of the functions required by the end user, and the functional requirements of the various items are derived by specifying them.

This is achieved by mapping / analyzing 1: N mappings to take advantage of the approach of developing mapped functional requirements (implementation functions) to meet the corresponding customer requirements.

In the same context as the priority in the customer requirements, the functional requirements specify the development difficulty for each requirement item, and formulate a system for research and development by specifying the development difficulty from the developer's point of view in the functional requirements.

In addition, a function evaluation method may be assigned to each functional requirement item to specify a method for evaluating the functional requirement after development and implementation.

This can be used as an evaluation means for each function in the future, and based on this, an index for judging satisfaction of functional requirements can be provided.

Meanwhile, the generated analysis model file and the product database for design are selected through the following process (S140).

That is, when a database is selected, a graphical user interface (GUI) for the characterization specification is operated (S142).

Here, the characterization specification refers to various types of products used in the feedback loop design process for the numerical results of a design product, which are used to select a suitable product after engineering design.

For example, a Korean industrial standard for a hydraulic cylinder prepared based on the International Standard Organization (ISO) regulations is shown in Fig. 8 (a), and the result defined by the product design method of the present invention is shown in Fig. 8 (b) Respectively.

The 'design' in each item in FIG. 8 (b) means the design value determined through the feedback loop design process, and 'select' means the design value defined by the product characterization specification.

Meanwhile, when the product characterization specification is inputted through the graphic user interface and the product database for the analysis model file and design is selected (S144), the inputted product characterization specification is temporarily stored (S146).

Then, as shown in FIG. 7, whether or not an analysis model for reconfigurable computing environment (RCE) interworking based on a graphic user interface is checked is checked (S150).

Here, RCE is an open source based software framework program that engineers and scientists use to integrate their own design and simulation tools to design and simulate complex systems (eg, aircraft, ships, satellites, etc.) do.

In other words, many analysts need a variety of analytical, design and simulation tools to deal with complex systems, and in a reconfigurable computing environment, these tools are integrated into the workflow.

RCE runs workflows, pulls results from related tool servers, and supports slightly different requirements and other scientific applications.

The original RCE platform was developed in Germany in the SESIS (Ship Design and Simulation System, 2005 ~ 2009) project and used in the German aerospace center. It is an open source form using the Java language. .

If an error of the analysis model is found in step S150, a warning and error message are displayed on the screen (S215) and the flow returns to step S120.

If an error of the analysis model is not found in step S150, a design variable to be used is selected (S210) and an initial value is set (S220).

Next, an objective function is selected (S230), an RCE model and an analysis batch file are generated (S240) and an RCE program is executed (S250).

At this time, the design work can be performed while checking the program result on the screen in detail through the graphic user interface on the screen. The instruction input to the operation terminal is expressed as a step on the screen, So that the conversion rule from the instruction input to the program is made uniform so that the designer can easily make the judgment and the design mistake is prevented.

As the RCE program is executed, batch simulation is performed (S251), and the objective function of the simulation result file is read (S252).

It is determined whether the read objective function of the simulation result file converges to the objective function selected in step S230 (S253).

If the read objective function converges on the selected objective function, the design result is displayed on the screen (S254). If the read objective function does not converge, the design variable is changed (S255) and the input file for analysis is modified (S256) (S251).

On the other hand, after the design result is displayed on the screen in step S254, the characterization specification information temporarily stored in step S146 is called up (S257).

Based on the displayed design result and the called characterization specification information, the optimized hydraulic cylinder product is selected from the database (S260) as shown in Fig.

At this time, the selection of the appropriate specification is based on a simulation framework program that can be applied commonly regardless of different environments of each shipbuilding marine industry, but also a database that can be customized according to different environments of each shipbuilding marine industry It is possible to expand it later.

In addition, since the user of the program is based on the graphic user interface, the program user can easily find an operation to be performed on the device or command to perform a desired operation from the screen to the icon, By observing the entire design process, it is possible to sequentially understand the operation of the device or command and the ideas generated thereby, and to execute the program, so that a large part of the designer's thinking work becomes mechanically actuated,

Product specification information such as thrust, inner diameter, rod diameter, and operating pressure of the selected hydraulic cylinder product, recommended vendor information, product name information, and the like are displayed on the screen as shown in FIG. 6 (S270).

9 is a data sheet of a hydraulic cylinder designed according to an embodiment of the present invention.

10 is a table classified according to the support type of the hydraulic cylinder among the data sheet contents of the hydraulic cylinder shown in Fig.

11 is a view showing an order format using the data sheet of the hydraulic cylinder shown in Fig.

As shown in Fig. 9, the data sheet of the hydraulic cylinder is classified into various types according to items such as packing material, support type, cylinder inner diameter, rod diameter, stroke, cushion type, piping position, cushion valve position, Your choices are listed.

For example, as shown in Fig. 10, the support type of the hydraulic cylinder can be classified into a basic type, an axial right angle food type, an axial food type, and a rod-side flange type.

In order to request a product design from a predetermined company, an order is placed in an order format including various features of the product as shown in FIG. 11 by using the data sheet of the hydraulic cylinder shown in FIG.

Therefore, methods for distinguishing the types of products for which the product design is requested include support types and applications, and the applications include general, high-pressure general, steel making equipment, telescopic, thin, rotary, circular, and special.

In the present embodiment, a case where a design is requested using a data sheet of a hydraulic cylinder is illustrated as an example. However, the design may be made using a butterfly valve data sheet, a ball valve data sheet, a bolt data sheet, have.

The design information for the product thus provided can overcome the disadvantages of the conventional feedback loop design technique that derives only the design for numerical information, so that the characterization specification described in the product data sheet, that is, various characteristics, We will provide accurate design information for the product by selecting the product of specification.

12 is a table showing a result of optimizing and reducing a large amount of data as a result of performing data filtering in a framework program according to the product design method of the present invention.

12, by setting the effective thrust to 29038 [kgf], the buckling safety factor to 1.5, and the minimum rod inner diameter to 77 [mm] by using the conventional feedback loop designing technique, the proper design of the hydraulic cylinder As a result, 207 massive amounts of data were filtered through the distinction of the product type, resulting in reduced results with 18 optimized equipment products.

As described above, according to the integrated design framework of the present invention and the product design method using data filtering, unlike the conventional feedback loop designing technique that derives only the design for numerical information, various characteristics described in the product data sheet are input , The vast amount of data that has been searched by the result of the simulation is filtered and greatly reduced to the optimized specification equipment products, so that the optimum specification product is selected and the accurate design information about the product is provided.

In addition, it is very useful for manufacturing suitable products by transferring appropriate design technology of advanced plant and large shipbuilding companies to a predetermined company with difficulties due to lack of equipment or manpower for designing required products.

In other words, in order to derive a design plan for a suitable product of an actual offshore plant equipment from a predetermined company, there is a great restriction due to the expense, difficulty of operation, complication of application, etc., and if the result of the applied plan is unsatisfactory, If a new attempt is repeatedly applied until it is derived, risk factors are very large in terms of cost and time required for development.

Therefore, if the present invention is utilized, a predetermined company can find the optimal stabilization plan with minimum cost and time, and apply it to the actual equipment of the offshore plant, thereby eliminating trial and error and saving the cost and time required for product development.

As described above, the integrated design framework and the product designing method using data filtering of the present invention can be applied to a product designing method in which a specification described in a data sheet of a product is input from a predetermined company, And the design information of the product is provided to a predetermined company by selecting the product of the optimum specification required by filtering the product with the specification of the product inputted through the distinction of the product type.

Through this, we overcome the disadvantages of the conventional feedback loop design method which only derives the design information for the numerical information and reflect the various characteristics described in the product data sheet to the design, so that a vast amount of data is filtered, And it is possible to select an optimum product.

In addition, designers can obtain design information for products with appropriate specifications at minimum cost and time, thereby preventing trial-and-error and reducing the cost and time required for product development.

In addition, product designers can perform design work with a graphical user interface, which facilitates designers' judgment, prevents design mistakes, and allows many parts of the designer's work to be mechanically actuated, saving manpower and time.
