| 摘 要： | 针对设备安装架结构进行了直升机环境的随机振动分析。首先讨论了直升机平台的振动环境特点，利用能量相等的原则将随机加正弦的振动谱转化为纯随机振动。然后利用Pro-E软件构建的三维模型，导入Hypermesh进行几何处理并划分网格，最后使用ANSYS软件进行有限元求解，得到结构在直升机振动环境下的位移应力响应，并对结构的动强度进行了校核。

| Abstract: | A random vibration analysis of mounting rack for helicopter-borne equipment was done.Firstly,the vibration environment of helicopter was described and the random plus sine vibration is transformed into pure random vibration by equivalent energy principle.Secondly,a three-dimensional model was built using software Pro-E,and the finite element model was built using software hypermesh.Lastly,analysis was done using software ANSYS.The dynamic response of a mounting rack was obtained,and the dynamic strength was... |
