Abstract

Aiming at the tracked vehicle with coupled pump-motor hydraulic steering system, the vehicle system coupling model based on MATLAB/Simulink was established under the braking, steering and straight driving scenario. The mathematical model of hydraulic steering regulation system with variable pump and quantitative motor is established. After analyzing the kinematics and dynamics of the tracked vehicle, the vehicle system coupling model under the above working scenario was established. The main performance parameters of the vehicle, such as track speed, steering radius, steering driving force and steering high pressure, are studied under the conditions of different variable pump swash plate inclination angle (different pump displacement), different vehicle braking force and different engine speed. The stability of the combined pump-motor hydraulic steering system is evaluated, and the correctness of the established model is verified, which has certain theoretical guiding significance for the research of the steering control strategy of tracked vehicles.
