摘要
文中针对某机载雷达发射机结构进行了机载环境的随机振动分析。利用ANSYS workbench软件建立了发射机的有限元动力学模型,完成了模态分析和随机振动分析,得到了在机载环境条件下的结构应力和变形云图,并对发射机结构进行了刚强度校核。
A random vibration analysis of an airborne radar transmitter is carried out in this paper. A finite el- ement model of the airborne radar transmitter is established by using ANSYS workbench software. Then the mode analysis and random vibration analysis are conducted in the actual environment condition. The stress dis- tributing graphs and deforming graphs are obtained. Finally, the stiffness and strength performance of thetransmitter are verified.
