Shock resistance analysis of a spaceborne electronic equipment

Abstract

In order to ensure the shock resistance of a spaceborne electronic equipment, this paper carried out finite element analysis and test the response acceleration of the shock test. According to the test data, dynamical response of each part of the system, which is consist of the spaceborne electronic equipment and the fixture, is analyzed. According to the analysis results, the failure risk of a electronic component is identified, and the mechanical design of this electronic equipment has been improved. With a weight increase of 0.4%, the maximum shock response acceleration of the electronic component in the electronic equipment has been reduced by 64%, the shock response acceleration meets the requirements of this electronic component, and eliminates the failure risk of structural and electronic components in the electronic equipment.
