| Abstract: | Aiming at the problem of low steering accuracy in the steering process of three-axis vehicle,with the help of the advantages of Newton-Euler method in multi-body modeling,the mathematical model of three-axis linkage steering mechanism is established,the position,angular velocity and force equations of the mechanism are derived,and the kinematic model and dynamic model are established by using MATLAB software and ADAMS software,The key points of the three-axis linkage steering mechanism are simulated and optimized through the joint simulation of Simulink and Adams.The simulation results show that after optimization,the steering accuracy of the three-axis linkage steering mechanism is improved,the angle error is reduced to less than 2.2°,and the force on each articulated point is more stable,which improves the steering stability. |
