The aircraft has severe mechanical conditions such as overload and vibration during operation. The environment in which VPX chassis are located is complex and harsh. In order to reduce the effect of high level vibration and shock on the VPX chassis in Flight Environment, the Strength Analysis of the whole chassis is made. Therefore the structure is modified according to the analysis result to improve its ability of anti-vibration and anti-shock. This paper proposes a iterative optimization method based on the variation characteristics of structural strength through iterative optimization, and by using the Finite Element Method for simulation calculation, the thickness of the area of the lugs of the equipment was adjusted to make the deformation and the stress and the weight suffices requirements of the design. It can shorten the period of product development and lower the product cost by the method presented in this paper.
