Abstract
Shock absorbers are widely used in airborne equipment as a kind of vibration damping device, but there are relatively few studies on the damping performance of shock absorbers using finite element analysis methods. The finite element analysis of the shock absorber mainly adopts the method based on material equivalent and spring damping element. From the perspective of engineering applications, this paper proposes a equivalent modeling analysis methods and correction procedures for shock absorbers with the random vibration conditions. The ANSYS Workbench was used to establish a finite element analysis model to analyze the vibration isolation efficiency of a airborne equipment vibration reduction design scheme. The experiment verified that the error between the finite element analysis result and the test result was less than 10%, which can meet the evaluation needs of the vibration damping design plan in the early stage of product development. The analysis method and correction process can provide important data support for the selection of shock absorber and the evaluation of vibration reduction performance in the design of vibration reduction system, and it has important engineering application value.
