高速船尾部喷推区域结构设计及强度和振动分析

本文针对某采用喷水推进型式的高速船,对其尾部喷水推进区域进行相应的结构加强设计,并分析局部强度及振动强度。运用MSC.Patran软件建立船体包含尾部喷水推进装置在内的有限元模型,综合考虑喷水作用载荷、船底波浪冲击载荷、舷侧载荷等设计载荷,对尾部局部强度及振动进行计算分析,结果符合设计要求,可为类似船型的船体尾部优化设计提供技术参考,具有一定的工程意义。

Structure design and analysis of strength and vibration of tail water jet propulsion unit of some high speed ship

For some high speed ship with water jet propulsion unit,the corresponding structure design of this area is proposed,and analyzed and calculated by way of example.The MSC.Patran software was used to establish the finite element model of the ship including the tail water jet propulsion unit.The design loads such as water jet force,bottom wave impact load and side load were considered.The total strength of ship and the local strength of tail were calculated and analyzed,which will provide support for the optimization design of ship in the next stage.
