Design and Numerical Simulation of Vibration Isolation and Shock Resistance for the Electronic Equipment on the Rockets

The severe mechanical environment faced by the electronic equipment on the rockets in its whole life cycle directly affects the electrical function, performance and reliability of the equipment. It is necessary to carry out vibration isolation and shock resistance design to improve the environmental adaptability of the equipment. Based on the practical experience, the basic design process of vibration isolation and shock resistance for military electronic equipment was proposed. An electronic equipment on the rockets was taken as the research object, the relevant design and numerical simulation of vibration isolation and shock resistance were carried out. Based on the brief introduction of its structure, the vibration isolation mode, the selection of vibration isolator and other design measures were discussed, and the numerical simulation was carried out with the finite element method. The results of numerical simulation and prototype test verified the effectiveness of the vibration isolation and shock resistance design measures. This provides reference for design and analysis of similar equipment.
