| Abstract: | In this paper a theoretical analysis has been made of the pressure feedback in speed regulation system of hydraulic haulage unit, and a mathematical model of the pressure feedback device composed of damping pipe and speed regulating cylinder, has been built up. The paper points out the difference between the models given by this paper and reference1], and gives method for determining the rational inside diameter of the damping pipe. It provides an theoretical basis for design of the damping pipe. |
