A two body towed system is especially considered in detail. The factors influencing the heave of towed-bodies, such as the weight of the towed-body (in sea water), the length and the weight (in sea water) per unit length of the cable between towed-bodies and towing ship, are investigated in detail. Calculations show that the two-body towed system can greatly increases the stability of the towed system.展开更多

Through the analysis of this system, a physical model is established, which describes the motion of the vehicle caused by the ship motion and wave motion. Furthermore, a mathematical model based on this physical model is obtained, and a numerical solution program is made. As an example, a practical launch and recovery system fbr an underwater robot is calculated by use of the program, and the motion track of the robot is obtained.展开更多
