摘要
采用功率键合图法,建立了地下管线液压换管机回转液压系统的数学模型;依据数学模型,运用动态仿真工具Simulink建立液压系统的仿真模型。仿真结果反映了液压马达入口压力和输入流量随时间的变化情况,为分析系统的动态特性提供了依据。
The mathematical model of the slewing hydraulic system of pipeline replacement machines that is used to replace underground pipelines has been established with the power bond graph method, and the simulation model of the hydraulic system by using the dynamic simulation tool Simulink has been built based on mathematical models. Simulation results reflected the change of the inlet pressure and input flow of the hydraulic motor with time, and provided a favorable basis for the analysis of the dynamic characteristics of the system.
