摘　　要：为计算远距离拖曳式试验系统中航行体的运动轨迹和姿态,分别建立了垂直面和水平面运动方程,使用龙格库塔法对方程组进行求解。初始垂荡位移、横荡位移、纵倾角、首摇角、纵摇角速度、首摇角速度对航行体运动稳定性影响较小,初始垂荡速度和横荡速度对航行体的稳定性影响较大。缆绳张紧力越大,航行体的稳定性越好。张紧力超过30k N后,稳定性改善效果不再明显。针对远距离拖曳式试验系统,选择30k N的张紧力比较合适。To compute body’s trace and attitude in a remote towing test system, motion equations both in vertical plane and in horizon plane were built and solved with Runge-Kutta method. Effects of initial heave displacement, swaying displacement, pitch angle, yaw angle, pitch angular velocity and yaw angular velocity on the stability of the body were small. But initial heave velocity and swaying velocity make great effects on the stability of the body. The greater the take-up force, the better is the stability of the body. When the take-up force is greater than 30kN, the stability of the body will not be improved dramatically. It is concluded that 30kN is proper for the take-up force in the remote towing testing system.
