Abstract：Elaborated the core part of hydraulic soft brake which can solve the brake question of the negative strength dragging mechanical system:electricity-liquid proportion overflow valve, analyzed the electricity-liquid proportion over-flow valve' s work mechanism, and carried on the simulation analysis for the dynamic characteristic of the electricity-liquid proportion overflow valve' s pressure-regulating system with the power band graph theory and the Matlab soft-ware. The simulation shows that pressure control characteristics of this valve has the great relations with the parameter of pressure-regulating system. The valve responds rapidly and has the good stability when the system parameter is ap-propriate. Used the Fluent software to carry on the internal flow field' s numerical simulation of electricity-liquid pro-portion overflow valve under certain working pressure, and obtained the fluid pressure and the speed change situation of this valve. The research indicates that this valve has the characteristics such as pressure regulating reliable, responds quickly, stable property and so on.
