Dynamic Analysis and Parameters Optimization of an Airborne Electronic Equipment Box
摘要
Abstract
In order to improve the environmental worthiness of airborne electronic equipment,the dy-namic analysis is considered as the key point in structural design.Taking an airborne electronic equipment box as the research subject,a finite element model of the box was established,and then the dynamic char-acteristics were analyzed to locate the weak links in its design.In addition,on the basis of the dynamic a-nalysis,the structural parameters were optimized by simulation.The numerical results indicate that the optimum design has made obvious improvement,as the mass of the airborne electronic equipment box was reduced by 14.5% without increasing the maximum equivalent stress of PSD.The method can provide some reference to engineering design.关键词
