Design and Application of Multi-body Dynamics Optimization Design Software Architecture

With the development of computer science, the optimization method has been widely used in the dynamic design process of complex multi-body systems. In the optimization design of complex multi-body systems in different fields, there are many problems, such as large amount of calculation, low efficiency and difficult optimization of complex optimization problems. In this paper, a multi-body dynamic optimization design software (MSTMM-OPT) is designed and implemented, which combines the transfer matrix method and the approximate model to realize the optimal design of single-multi-objective problems. The software has the main functions of sensitivity analysis, experiment design, approximate model construction, optimization and solving, and realizes each function and corresponding post-processing result display function combined with interface design. The software can realize the optimization design of complex systems. By calculating a series of standard test functions, the software is compared with the similar multidisciplinary optimization software ISIGHT software, which shows that the main functions of the software are equivalent to those of similar foreign software.
