舰艇电子设备需要满足颠震、高压等多种恶劣环境，本文为了验证和优化结构设计，创建某舰艇多模态数据处理电子机箱的三维模型，适当加工后导入有限元软件开展机箱模态、随机振动、谐波响应、颠震冲击分析。试验结果表明，机箱侧面通风板和输出滑板边缘区域应力和变形较大，但在各工况下都不超过机箱的许用应力上限，可靠性较强。某舰艇多模态数据电子机箱的仿真研究对于优化及机箱结构和抗震性能，增强舰艇隐身性，改善生存能力有重大意义。
The electronic equipment of ships often needs to withstand various harsh environments such as shock and high pressure. To verify and optimize the structural design, a three-dimensional model of the multi-modal data processing electronic cabinet for a certain ship was created. After appropriate processing, it was imported into the finite element software for conducting analyses of the cabinet's modal, random vibration, harmonic response, and shock impact. The test results show that the stress and deformation in the edge area of the side ventilation plate and the output slide plate of the chassis are relatively large, but they do not exceed the allowable stress limit of the chassis under all working conditions, indicating strong reliability.The simulation study of the multi-modal data electronic cabinet for a certain ship is of great significance for optimizing and improving the structure and seismic performance of the cabinet, enhancing the stealth capability of the ship, and improving its survival ability.
