ProE finite element software is used to establish mechanical linkage model, and ABAQUS simulation software is used to perform static strength simulation analysis of the established linkage model, which verifies the safety of mechanical linkage under specific working conditions by extracting the load on the components, and optimizes the connecting rod structure model to seek lightweight solutions. The modal simulation analysis, stress and strain simulation analysis and lightweight topology optimization design of the mechanical connecting rod are mainly carried out by using ProE and ABAQUS simulation software. The results show that the design connecting rod model and the optimized model meet the permissible stress requirements under the relevant working conditions, and the topology optimization design also provides a better structural design idea for the product. Through the simulation analysis of the mechanical connecting rod, the stress distribution and component performance safety of this type of connecting rod under working conditions are obtained, and the linkage design mechanism is optimized, which proves the practicality of ABAQUS simulation software in the design, analysis and optimization of components.
