Structural analysis of the radar signal simulator back-plane

摘要

LRM (Linear Replaceable Module) structure is a new generation of high-reliability avionics system is based, and in the other comprehensive electronic system design are also beginning to use. In practical applications, according to the structure of RF-based LRM standards for integrated electronic system back-plane radar signal simulator has been designed, but not informed LRM module installation back-plane carrying capacity. In this paper, finite element analysis software module for installation LRM radar signal simulator back-plane structure static analysis, get back the maximum deformation position and the amount of deformation, the maximum stress intensity position and stress values. According to the relevant aviation industry standards, the analysis shows that the back-plane architecture designed to meet the strength requirements of LRM.
