摘要
针对时域分析方法计算效率低和动态设计分析方法不能得到设备冲击响应变化规律这一缺陷,提出了舰船设备抗冲击响应的瞬态模态动力学分析方法。以某型舰船设备为例,采用时域分析法和瞬态模态动力学方法对该设备进行抗冲击模拟,对两种方法下该设备的冲击响应进行比较分析。研究结果表明:瞬态模态动力学方法是一种有效的舰船设备抗冲击性能分析评估方法。
For the low efficiency by time-domain analysis method and no shock dynamic response law by dynamic design analysis method,transient modal dynamic method applied to the naval equipment anti-shock performance analysis is proposed.Taking a shipborne mechanical equipment for example,the anti-shock numerical simulation is carried out using timedomain analysis method and transient modal dynamic method.Shock responses of the naval equipment are compared under above two methods.The research results show that transient modal dynamic method is an effective naval equipments method for anti-shock performance assessment.
