摘要

摘要: 为建立一种简单而又适用的鱼雷壳体楔环连接结构模态计算分析模型, 将楔环连接的鱼雷壳体简化为2个壳体以及1个环形圈连接的有限元模型, 其中包含7对接触面以及1个接触刚度参数。通过鱼雷壳体的静力加载试验以及静力仿真对比, 辨识出模型中的接触刚度参数。对修正后的有限元模型进行模态仿真计算, 仿真模态频率与试验模态频率误差不大于2.65%, 结果表明了该模态计算方法的准确性。可为鱼雷壳体等含楔环连接结构的有限元建模与模态分析提供借鉴。

Abstract: The torpedo shell joined with wedge-ring connection is simplified as two shells and one annular ring. This simple structure is modeled to build a simple, applicative finite element analysis model, which contains seven contact surfaces and a parameter of contact stiffness coefficient. Static loading test and static simulation analysis are conducted to identify the contact stiffness of the model. The modal of the modified model is calculated via simulation, and the relative error of the modal frequency between simulation and modal test is not more than 2.65%, verifying the accuracy of the proposed modal simulation method. This study may provide a reference for finite element modeling and modal simulation of the structures with wedge-ring connection, such as torpedo shell.
