On responding characteristics of full power hydraulic braking system for underground wheeled vehicles

The requirements for dynamic characteristics of full power hydraulic braking system are different from conventional hydraulic system. Taking the problems occurring during design and research of underground wheel vehicles, the mathematical model of hydraulic lines of full power hydraulic braking system was established by using bode graphs theory, then a dynamic simulating model of responding characteristics in full power hydraulic braking system with the hydraulic lines was established. By combining the means of simulation and test, the impact of piping layout of braking system on the dynamic characteristics of the system is analyzed and the simulating model is also verified. The rules that the pipe material, length and diameter use to affect the responding characteristics of braking pressure are learnt and corresponding improvements are suggested, which achieved predicted effects via implementation. The result provides a reference to the application and design of full power hydraulic braking system to domestic wheeled vehicles.
