- Ahmad et al. IFAC-PapersOnLine 48-3 (2015) 1726-1731
- the focus is on virtual prototyping, which is particularly useful in the design and development process of the preliminary check of
- Assembly processes on existing assembly modules for maintenance purposes and in particular a derivation and display of necessary assembly or disassembly steps that are necessary to gain access to a component of a complex assembly module, as well as documentation of current maintenance statuses with work carried out and the degree of utilization of components of the assembly module so far hardly noticed or implemented.
- the virtual working environment has a display device and a computing device, the computing device being connected to a storage device in which the properties of the complex assembly module and its components are stored with the assembly sequence.
- the process has the following steps:
- the proposed method enables a simplified implementation of
- Installation steps and their sequence are calculated and sent to a maintenance mechanic
- the proposed method is used to carry out maintenance work using a virtual work environment on a complex assembly module.
- the virtual one is a virtual work environment on a complex assembly module.
- the working environment has a display device for displaying the available and calculated information and a computing device which processes this information.
- the computing device is connected to a memory device in which the properties of the complex assembly assembly and its components are stored, in particular also in connection with their assembly sequence.
- a virtual model of the complex assembly module is present in the memory device, which has a volume model that can be represented by the display device for each relevant component.
- Storage device further the components or component groups (within the scope of the description of the invention, for simplification, component groups, which in their entirety represent a smaller functional unit of the complex assembly assembly, also summarized under the term component), are stored, such as
- Assembly module assigned.
- the assembly relationships are clearly defined by the link logic.
- the link logic for example, specifies which components must first be removed to remove any other component.
- the properties of components stored in the memory device are in particular also during the implementation of the proposed method for performing
- Maintenance work can be modified.
- the virtual working environment is used to diagnose components, the result of which is stored directly in the storage device of the virtual working environment and is available for carrying out the further maintenance work.
- information on the condition of a component can be stored, such as positions and types of existing damage, which can be marked directly on the virtual component and the dimensions of which can be specified. If necessary, photos or measurement results of the damage can also be stored in the storage device.
- a first step a at least one component to be serviced or a predefined modification status of the assembly assembly is selected in the virtual working environment.
- This step can be carried out, for example, by a maintenance planner who plans to carry out the maintenance in advance, or directly by a maintenance mechanic who is already working on the maintenance of the assembly module and, for example, preparing at least one further maintenance step resulting from the maintenance work.
- others can also be carried out in the same way
- a modification status is a defined structural state of the complex assembly module, for which it is precisely defined which components of the assembly component are mounted on the assembly component in this modification status, and which ones are disassembled.
- Computing device back to the data stored in the storage device, such as, in particular, the linking logic of the components.
- the optimal sequence of disassembly and assembly steps is also calculated.
- a tailor-made Work sequence are calculated, in which simulation sequences of the dismantling instructions can then also be integrated, for example.
- Disassembly steps are displayed, which are required to gain access to a component to be serviced or to achieve the selected modification status.
- a suitable display of all available information and calculated data must be selected, which one
- Assembly module performed disassembly or assembly steps documented in the storage device.
- work steps carried out can be saved directly in the virtual work environment.
- This can, for example, be carried out directly by a maintenance mechanic by means of an electronic acknowledgment, as a result of which the documentation and archiving effort for maintenance work carried out can also be reduced.
- the complex assembly assembly could be displayed on a display device in addition to the maintenance work, with the component to be serviced in the
- the availability of the at least one component to be serviced is also checked in step b) and displayed in step c). This means that any components that may need to be replaced can be compared with the stocks before the maintenance work on the assembly module is started. This enables an early check to be made as to whether sufficient spare parts are available if necessary. This increases planning security and reduces delays in the course of time
- the properties of the components of the assembly group stored in the memory device have the current maintenance status of the component.
- a current status report of the assembly assembly is available.
- a progress report can be created in connection with the documentation of current dismantling or assembly steps and the associated linking of component properties. This enables improved, targeted work planning.
- the disassembly or assembly progress of the assembly module can also be visualized, for example, by color coding the components.
- a modification status is a defined assembly state of the complex assembly module, for which it is precisely defined which components the
- Assembly assembly are mounted on this assembly and on the assembly assembly, and which are disassembled. The assignment of components to a predefined one
- Modification status makes it easier to define the current assembly situation, especially when the complexity of a complex assembly module increases, so that a predefinition of modification statuses reduces the complexity of the description and
- step b) also takes place
- Predefined assembly packages included, in which predefined dismantling or
- Assembly steps and their sequence for assembling or disassembling components of the assembly assembly are defined.
- the dismantling or assembly steps are defined with their sequence, which are required to convert the assembly assembly from a first modification status into a second
- an assembly module has a predefined modification status after execution of at least one predefined assembly package.
- the proposed procedure also makes it possible to use the virtual work environment to achieve a desired modification state of the assembly module. Starting from a first modification status, the required assembly packages are determined, by means of which the desired second modification status can be achieved.
- One or more assembly packages carried out one after the other usually represents the most economical disassembly or assembly process that is required to achieve a predefined one
- Damage analysis of the assembly assembly is possible in the virtual working environment directly on the assembly module shown on a display device, depending on the analyzed area of the assembly module, certain modification statuses or individual modules of the model can also be represented, or for example also sectional views. In this way technical relationships can be more easily recognized and understood, which would only be recognizable if the assembly module had been completely disassembled without the proposed method. In this way, potential causes of errors can be identified and a targeted inspection and disassembly can be planned before dismantling the assembly module.
- a work plan is created in step b), which is output in step c).
- a mechanic can be tailored and the dismantling or assembly of the affected engine area can be specified step by step.
- Digitally created documents can be uploaded, for example, to screens, particularly in production, as well as to mobile devices.
- the work plans can be provided with interactive control and graphic elements, such as animations of the dismantling or assembly steps, exploded and detailed drawings or short videos that explain particularly complex work steps.
- Such work plans can also be created, for example, according to a modular principle.
- the display device is a display, virtual reality glasses or a head-up display.
- support information for the respective work step can also be fed directly into the projection area of the display device as so-called augmented reality information.
- simulation sequences of the dismantling or assembly instructions can be integrated into the individual work steps, for example, which the mechanics can load onto a suitable display device.
- a virtual work environment for performing maintenance work on a complex assembly module in particular a gas turbine
- the virtual working environment has a display device and a computing device, the computing device being connected to a storage device in which the components of the complex assembly module with their assembly sequence and their properties are stored.
