摘要
对水下航行器舷外附体在流体冲击下的振动特性测试方法、数据分析方法进行了介绍,并开展了以实测数据为基础的舷外附体振动特性的分析研究,得到了实测情况下的水下航行器舷外附体振动分布特性及其变化规律,并对舷外附体在流体冲击下的共振情况进行了简要介绍。对水下航行器的减振改进设计具有积极的作用。
The paper introduced the measurement of vibration characteristic for outboard fittings on underwater aircraft produced by current impulse and the analytical method about data,and based the actual noise detected data,the vibration characteristic is researched and analyzed,and the vibration distributing character of outboard fittings on underwater aircraft and its variety regulation,beside the resonance vibration caused by the outboard fittings is impacted form water is introduced briefly.It has postive effect for damping project of underwater aircraft.
