| Abstract: | The hydraulic tamping and drawing device which is controlled by pressure feedback was introduced. The author analyzed the course of tamping and proposed a mathematical model of the hydraulic system. The model could be directly used in numerical calculation and simulation, and the simulation result was very close to the experimental one. It was verified that the impacting energy and frequency can be adjusted independently and steplessly by timely adjusting the impacting pressure of hydraulic system with the varying resistance of the vertical post. The hydraulic tamping and drawing device controlled by pressure feedback can save energy and raise the tamping efficiency. |
