水下运载器调节索抗流功能的数值计算与分析

Numerical calculation and analysis of anti-current function provided by a heavy rope on underwater vehicle

调节索是从水下运载器悬下的重型链条,能够在运载器悬停于水中时起到辅助抗流的作用。文中给出了调节索实现抗流功能的控制方程,并对方程中用到的运载器纵向阻力系数、垂向运动时的水动力系数及附加质量进行了数值计算,最后给出了调节索长度及重量对运载器抗流调节范围的分析结果。

Abstract：A heavy rope hung from underwater vehicle can help resist both horizontal and vertical currents. The control equations which can fulfil anti-current function of the heavy rope were proposed. Numerical cal- culation of transverse friction factors, vertical hydrodynamic force factors and added mass utilized in the e- quations when underwater vehicle moves in horizontal and vertical directions was also carried out. Finally, the analysis results of underwater vehicle anti-current adjustable range by different length and weight of the heavy rope were given.
