摘　　要：抗冲击性是舰船设备的重要指标之一。该文对一款设备的悬臂结构进行抗冲击优化设计,首先通过UG建立了装置的三维模型,利用正负三角波将冲击输入谱转化为加速度时间历程曲线;然后采用时域分析的方法对悬臂结构的抗冲击性能进行了有限元分析,根据得到的结果对悬臂结构上的薄弱部位进行了优化设计;再通过对优化后的模型的仿真分析,最终证明了优化的可行性,为后续的悬臂结构抗冲击设计提供了参考建议。The impact resistance is an important indicator for the ship equipment.In this article,the three-dimensional model of a device′s cantilever structure is established by using UG,and the impact input spectrum is converted into an acceleration-time history curve by using the positive and negative triangular waves.The finite element analysis on impact resistance of the cantilever structure is conducted with the time-domain analysis method.Based on the obtained analysis results,the weak parts on the cantilever structure are optimized for design;then the simulation analysis is conducted on the optimized model,and the feasibility of optimization is thus demonstrated.It provides reference suggestions for the subsequent impact resistance design of cantilever structures.
