| Abstract: | The power linkage map method was researched and applied to establish a dynamic model of rotary hydraulic system for the mine roadheader.According to the actual operation conditions of the rotary system in the roadheader,two performances of the power linkage maps were established.One is the dynamic model with a hydraulic cylinder buffer device and the other is a dynamic model with a overflow buffer.A simulation was conducted for the dynamic model with the simulak.The resuhs showed that the simulation results were good, which could provide the theoretical references to the design of the rotary hydraulic system for the mine roadheader. |
