Aerospace product general assembly technology simulation analysis method

Abstract

The invention provides an aerospace product general assembly technology simulation analysis method. A three-dimensional virtual reality environment serves as a platform, after the aerospace general assembly technology is planned and each procedure is designed, the aerospace product general assembly environment is established according to the actual general assembly situation, and overall process simulation of each procedure, trial assembly of relevant parts and inspection and verification of feasibility, safety, operating comfort and the like of the assembly scheme are conducted. By the adoption of the method, technologists get rid of dependence on experience to a certain degree, the general assembly process is simulated in the three-dimensional virtual reality environment through a digital model of an aerospace product, the overall process simulation verification is conducted on the general assembly technology scheme, the problems of assembly sequence errors, part interference, wrong installation, neglected installation and the like existing in the assembly process are found in time, the general assembly technology design scheme is corrected and optimized in time, the technology planning difficulty is lowered, and the technology scheme is more optimized.

Description

technical field [0001] The invention relates to the technical field of aerospace product design, in particular to a simulation analysis method for an aerospace product assembly process. Background technique [0002] The research and development of aerospace products needs to go through three major stages: product design, process design and manufacturing. Process design is divided into component manufacturing process, assembly process and other heat treatment processes, etc. As an important content in process design, assembly process design is mainly used to guide the assembly process of components. However, the final assembly process designed by the designer is not necessarily feasible, so simulation is required to verify whether the existing process plan is reasonable. Through simulation, some analysis reports can be generated for the existing process plan, and these analysis reports show that the existing final assembly Whether there is any problem in the process plan, th...

Problems solved by technology

[0004] (1) The assembly process is basically completed by traditional manual methods. This method requires workers to have high skills and operating experience. This over-reliance on individuals leads to frequent assembly quality problems, reduced assembly efficiency, and low assembly efficiency. longer period

[0005] (2) The discovery of design problems often needs to be completed through physical trial assembly and physical inspection after assembly, which leads to a series of problems such as longer development cycle and increased resource consumption

[0006] (3) Due to the influence of factors such as production organization mode, working environment, and unreasonable assembly process plan, the labor intensity of workers is high and job satisfaction is reduced.

[0007] (4) The traditional 3D virtual assembly simulation is only a visual assembly simulation of the final assembly process. In the existing simulation implementation process, no further consideration is given to the assembly accessibility, visibility and operation of assembly workers during the assembly process. Comfort and other issues, this traditional assembly process simulation is inconsistent with the actual assembly process, and it is impossible to design an assembly process that is in line with the actual human operation process

In addition, due to the lack of corresponding analysis for human operation accessibility, visibility and operating comfort, it is impossible to evaluate and screen different assembly schemes of products, so it is impossible to adjust and improve specific assembly processes, and it is impossible to Design the final assembly process that conforms to the actual operation process of people

[0009] The above-mentioned problems in the general assembly process of aerospace products have not been effectively resolved. The root cause is that the final assembly process design stage did not make full use of 3D virtual simulation technology for final assembly process verification, and seldom considered human factors and human assembly requirements. , failed to fully consider various unknown disturbances in the actual assembly in the design stage, and the theory and method of human factors engineering were not applied enough in the production system of aerospace products
