Chinese Abstract

针对水下航行器在流体中由于流固耦合所产生的附加质量问题,在用高等流体力学对附加质量进行描述的基础上,利用模态参数识别理论,提出了根据实测模态参数来识别水下航行器附加质量的方法。该方法不但可以计算总的附加质量,而且可以计算其分布情况。

English Abstract

Aiming at the underwater vehicle in fluid because of problem that fluid and solid coupling produced added mass, in using advanced hydrodynamics to proceed to the added mass the foundation that described, and using modal parameter design theories, the paper put forward according to modal parameter test data identified the method that added mass of the underwater vehicle. The method not only calculated the whole added mass, but also could compute its distributing on the underwater vehicle.
