Abstract潜射导弹高速弹射出水时,空泡溃灭产生较大的冲击载荷,对导弹的结构强度提出了挑战。同时现代导弹的设计要求对结构进行优化设计,对弹体的厚度、质量均提出了要求,因此更加精确地计算导弹出水过程中的结构响应能够为设计人员提供更准确的参考。基于导弹局部段细致有限元模型得出的非线性刚度参数,将局部段等效为一具有非线性刚度的梁单元,并入建立的导弹出水全过程虚拟样机模型进行计算仿真,将结果与之前线性刚度模型的计算结果进行对比,最后对该局部段非线性因素对全弹整体响应的影响进行讨论。
Other AbstractLarge bending moment is produced due to bubble collapse when submarine-launched missile is ejected to pierce the water with high speed,which challenges the strength of the missile structure.At the same time the structures of the missile should be optimized according to the design principles of the contemporary missiles with the requirements of shell thickness and mass.Therefore,more accurate calculations of the dynamic response in the process of missile piercing water are needed for designers.This article s…
