摘要
利用功率键合图建立掘进机行走机构液压系统的动态数学模型,在Simulink环境下进行仿真,分析系统的动态特性。为进一步改进和完善掘进机行走机构提供了理论依据。
Using the power-bond graph builds the dynamic mathematic model of hydraulic system for element of roadheader＇ s walking mechanism. The simulation of hydraulic system is carried out in Simulink environment, then analyzes the dynamic characteristic of system. The theoretical basis for further improving and perfecting roadheader＇ s walking mechanism is provided.
