摘要

考虑超空泡航行体头部受到的轴向扰动载荷作用,推导了水下航行体动力失稳控制方程,进而利用Bolotin方法对水下航行体的动力稳定性问题进行了数值计算,得到了相应的临界频率曲线,并分析了载荷参数和航行体参数变化对主动力不稳定区域的影响规律,计算结果可为水下航行体的安全评估提供一定的理论依据。

Abstract

The axial disturbance on the head of supercavitation vehicles is considered, and the governing equations for dynamic stability of submarine vehicles are derived, then the numerical calculation for the dynamic instability problem of submarine vehicles is performed by Bolotin’s method, corresponding curves of the critical frequency are obtained and the effects of the load parameters and the vehicle parameters on the primary unstable region are analyzed, the results provided a sort of theory foundation for the security evaluation of supercavitation vehicles.
