Simulation of full power hydraulic brake system for engineering vehicles

摘要

Considered the high speed, heavy weight, heavy load and fast brake of heavy vehicle, the scheme of full power hydraulic brake system controlled by dual brake valve is adopted in the brake system which can accomplish steering brake and emergent brake for engineering vehicle. The nonlinear mathematic models of components for brake valve, brake cylinder, connecting pipeline and so on are established to the full power hydraulic brake system. The double pipelines steering brake and parking brake are discussed by simulation experiment based on Matlab/Simulink. The simulation results proved the rationality to develop the double pipelines for brake system.
