Abstract

In view of the large impact force of the gas rudder at the starting moment, the joint simulation of dynamic analysis and finite element analysis of the transmission mechanism was carried out by ADAMS and ANSYS, the impact force of adjacent parts under variable load was obtained, and the transient dynamic response of the dangerous part was analyzed. The results show that within a certain range, the response speed of the impact force becomes slower with the increasing response time, and the maximum and minimum values are basically the same. The mathematical model of the gas rudder system was established, the PID control simulation analysis of the system was carried out in MATLAB Simulink, and the motion control experiment of the monolithic rudder system was carried out based on the simulation results. The experimental results show that the control platform can achieve good control effect.
