摘要
从理论上分析了水下航行体动态特性的频响函数合成方法。并基于 LMS动态测试与分析系统 ,对某导弹模型进行了模拟试验 ,得到了空气和水两种介质环境下导弹模型结构的模态特性 ,试验结果反映了附加质量对结构动态特性的影响关系 。
In considering the dynamic properties of missile that launching from submarine, this paper propose a method of FRF synthesis theoretically. With scaled model of a missile, experiments have been carried out using the dynamic testing system LMS, and the modal characteristics of missile are obtained both in air and under water. Results of test indicate the influence of added mass of water on the structure under water, and the method provided herein are to be feasible and effective according to the experiments.
