Dynamic analysis of steering system of the articulated vehicle in the heeled status

AbstractIn order to research the dynamic characteristic when the articulated vehicle accelerates, brakes and steers, it is necessary to analyze the force of the front and the rear car body and establish the steering dynamic mathematical model and simulation model when the articulated vehicle is in the heeled status. Taking the FW - 6 underground service car as an example, the results of the numerical simulation when the initial velocity of the vehicles is 12m/s, the heeled angle of rear car body is 0° and the heeled angle of front car body is 8° show that the dynamic responses of the steering acceleration, steering angle and steering speed are strong, at the same time, the vehicle steering stability is seriously impacted
