Dynamic simulation and experiment of a full power hydraulic braking system

Dynamic characteristics of a full power hydraulic brake system are directly related to the safe travel performances of vehicles. On the basis of the structure and performance analysis of a serial hydraulic brake valve, a simulating model of responding characteristics in a full power hydraulic brake system was established, and the simulation analysis of various structure parameters of the braking valve affecting the dynamic characteristics of the system was conducted. Experiments were conducted to verify the simulating model, to learn the affecting laws of many different brake means of vehicles on response characteristics of the system. The quality of the deigned brake system and its parts for construction vehicles has, through industrial utilization, met the requirement of ISO 3450.
