Abstract:

The application fields,such as aeronautics and astronautics,require high performance of contactor in vibration and other endurance environment.In this paper,the optimization design of the contactor vibration index is studied.Through the finite element simulation calculation,the weak points in the structure of the auxiliary contact components of the contactor are obtained,and the improvement direction and expected improvement effect are determined through the virtual prototype simulation,which provides a theoretical basis for the optimal design of the contactor vibration index.According to the calculation results,the vibration index of the contactor is improved obviously,which fully demonstrates the effectiveness of the optimization design method.The performance of the optimized product is obviously improved,which can meet the needs of use.

Key words: contactor, auxiliary contact, vibration, finite element analysis
