摘要
分析了汽车起重机变幅机构液压系统的结构及工作原理,运用功率键合图理论建立了汽车起重机变幅机构液压系统的功率键合图模型,并转化为控制工程领域的方块图,建立了动态模型,从而得到了系统的动态特性。运用MATLAB/Simulink工具箱对系统进行仿真,研究响应对整个系统的影响。
The structure and operating principle of the hydraulic system of a crane jib lubbing mechanism were analyzed.With the theory of bond graph,the power bond graph model of the hydraulic circuit was established,and translated into the block chart.The dynamic model of the system was set up,and the dynamic response of the system was obtained.MATLAB/Simulink was used to simulate and analyze the influence of the dynamic response on the hydraulic circuit.
