摘要
悬挂系统作为吊舱与飞机连接的主承力结构,其强度及刚度特性必须满足相关设计指标要求,才可以保证飞机在各种飞行状态下,吊舱内装设备能实现正常工作.此外,还要求悬挂系统设计满足轻量化要求.文章基于上述设计要求,对某机载吊舱悬挂系统进行结构设计,同时利用有限元分析软件对吊舱进行模态和动力学分析,并参照仿真计算云图对悬挂系统的薄弱区域进行优化改进.通过有限元仿真计算可知:优化后的悬挂系统刚强度较原设计得到明显提高.
Abstract
As the main load-bearing structure connecting the electronic pod to the aircraft,the strength and stiffness character-istics of the suspension system must meet the relevant design index requirements to ensure normal operation of the equipment installed in the electronic pod during the flying process of aircraft under a variety of flight conditions.In addition,the suspen-sion system is also required to be lightweight.Based on the above design requirements,the structure of an airborne electronic pod suspension system is designed,while the modal and dynamics analysis of the structure are carried out by using the finite element analysis software;and the weak areas of the suspension system are optimized and improved with reference to the simu-lated calculation cloud map.The strength and stiffness characteristics of the optimized suspension system had significantly im-proved compared with the original design through the simulation results.
