In our research and engineering design, we widely use professional 3D design and analysis software to conduct stress, deformation and fatigue analysis on key parts and parts of the product, optimize the design scheme and improve the design quality. Realize the conversion from 3D design drawing to 2D construction drawing to improve work efficiency and design accuracy. The simulation mathematical model is established to simulate the dynamic process of key equipment, verify the design results, and improve and perfect the design scheme.
