水下航行体舵板张开特性研究与分析

在对流固耦合仿真计算方法分析的基础上,建立起水下航行体舵板张开过程的仿真计算模型,采用该模型 对舵板张开过程的角速度、载荷以及响应等变化规律进行了研究。在水下航行体发射试验中,对舵板张开角度、舵 板应变等参数进行了测试,对测试获取的数据与仿真结果进行了对比分析,研究表明二者一致性较好,能够为水下 航行体的水弹道分析和舵板的结构设计、材料选择等提供指导。

Research and Analysis for Opening Property of the Rudder Plank on Underwater Vehicle

Based on the analysis of fluid-structure interaction method, the numerical simulation modular for rudder plankopening was built. With this modular, the research for change rule of the angular velocity, the load and the responding onthe opening rudder plank of a certain underwater vehicle was carried out. In the underwater vehicle launching test, the an.gular displacement-time curve and the strain-time curve were measured. Meanwhile, the test data and simulation calcula.tion data were compared and analyzed. The research showed that the calculation data coincided with the test data, so thesedata could offer advice for the analysis of trajectory analysis, structure design and material choice.
