同步发电机组的抗冲击动力学分析

舰船冲击环境主要是水下爆炸、武器直接命中、自身发射武器爆炸和核爆炸冲击波作用于船体的结果。它的传递特性是位移、速度、加速度和持续时间。舰船装备的抗冲击考核目前有冲击试验、静力学分析、动力学分析和冲击试验与动力学分析的组合4种方法。舰船装备进行抗冲击考核的目的是检验战时环境下装备承受上述冲击载荷的能力。论述了同步发电机组的抗冲击动力学分析以及这种分析方法的优点和局限性。

On Resisting High Impact Shock Dynamics Analysis for Shipboard Synchronization Generator Set

Navy ships may be subject to shock generated by non-contact underwater weapon explosion,contact weapon hits,self-delivered weapon explosion and nuclear blast.The shock environment is the physical result of non-contact explosion,contact explosion or nuclear blast which impart rapid displacement,velocity and acceleration to the ship structure.The high impact testing means have four types for shipboard equipment:shock test,static analysis,dynamics analysis and static analysis combined with dynamics analysis.The purpose of high impact testing for shipboard equipment is to verify the ability of shipboard installations to withstand shock loadings,which may be incurred during wartime service due to the effects of nuclear or conventional weapons.The article,dynamics analysis of resisting high impact shock for shipboard synchronization generator set is presented,and the advantages and shortcomings of this analysis method and discussed.
