Abstract
In this paper, the load simulation of tracked vehicle disc brake in low speed is discussed. The simulation of the resistance load and the control of the disc brake is researched when the resistance load loading on the test bench The simulation results show that, by controlling the input voltage of the disc brake electrohydraulic control portion, the disc brake braking torque can be controlled, the driving resistance simulation of crawler vehicle is realized. At the same time, the simulation has high accuracy, fast response speed, and has better dynamic characteristic. When the tracked vehicle is at the process of start, acceleration, deceleration, braking, steering , the engine and the transmission system mainly are in an unstable vehicle system dynamic, the load is dynamic load must be given. In order to investigate the performance of tracked vehicle HMCVT, a dynamic load [1] in the test system to simulate the loading process of tracked vehicle. Eddy current dynamometer can simulate the load [2,3] during a vehicle running a higher speed , the driving load in low speed ( including zero speed ) is simulated by disc brakes .
