The Mechanical Property Analysis of Sonar Probe and Cable in Aviation Winch

In order to accurately simulate the movement of the cable and the sonar probe during the operation of the aviation winch, the force on the cable and the sonar probe are analyzed based on the knowledge of mechanics in this paper, and the differential equation of the cable and the mathematical model of the probe are established. The nonlinear differential equation of the cable is deduced and solved by quasi-Newton method, thus the shape of each node of the cable and the attitude of the probe are iterated. Through simulation and its results, the influence of drag speed on the angle of the sonar probe and the shape of cable is analyzed, and the accuracy of the algorithm in the paper is proved.
