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。
In this paper, a stochastic vibration analysis of airborne radar transmitter structure is carried out. The finite element dynamic model of the transmitter was established by using ANSYS workbench software. Modal analysis and random vibration analysis were completed. The structural stress and deformation cloud images under airborne environment were obtained. nuclear.
