摘　　要：本文以某型舰船显控台为研究对象,为解决显控台整体结构设计强度满足电子设备环境适应性冲击试验的要求,对显控台的三维结构设计模型进行Ansys有限元分析。首先创建相应的有限元模型,并施加实际工作环境下的冲击约束条件,然后针对有限元模型,逐步开展瞬态动力学仿真分析和谐响应仿真分析。最后得到显控台受冲击载荷和外部激励作用下的应力和位移。针对显控台受冲击载荷和外部激励作用后应力和位移较大的部位开展结构优化,满足电子设备环境适应性冲击试验的要求。This paper takes a certain type of ship display console as the research object. In order to solve the overall structural design strength of the display console to meet the requirements of the environmental adaptability impact test of electronic equipment. An Ansys finite element analysis was carried out on the three-dimensional structural design model of the display console. First, the corresponding finite element model is created, and the impact constraints under the actual working conditions are imposed. Then, according to the finite element model, the transient dynamic simulation analysis and harmonious response simulation analysis are gradually carried out. Finally, the stress and displacement of the display console under the impact load and external excitation are obtained, and the structural optimization is carried out for the parts with large stress and displacement after the display console is subjected to the impact load and external excitation, which meets the environmental adaptability impact of electronic equipment.
