摘要
利用有限元建模和数值仿真的方法,对某一型船的长轴系进行抗冲击动态分析,得出该轴系在水下非接触爆炸时的位移和力响应,分析了不同冲击输入条件下轴承刚度对抗冲击能力的影响,对轴系抗冲击设计技术有实际指导意义。
A dynamic anti-impact analysis of a ship' s long shafting is carried out with finite element model setting method and numerical simulation method, the displacement and stress of the shafting during underwater non-contact blast are obtained, the effects of bearings' rigidity on anti-shock capacity in different shock input conditions are also analyzed, which will be a reference for the anti-shock design of shafting.
