摘要
分析了电液闸阀系统的工作原理,利用功率键合图理论建立系统的数学模型,并在MAT-LAB环境下编写了M函数对该系统进行了数字仿真,分析液压缸的瞬态响应特性。发现在负载恒定、输入流量变化时和输入流量恒定、外负载突然减少时,液压缸产生速度不稳定,但速度波动对系统冲击较小,不易发生水锤现象。
The paper analyzed the working principle of the electric and hydraulic brake valve system.A mathematical model of the system was established with the power linkage drawing theory.The digital simulation on M function to the system under the MATLAB environment.The paper analyzed the transient response features of the hydraulic cylinder.It was found that when the loading was constant and the input flow varied or when the input flow was constant and the outer loading suddenly decreased,the hydraulic cylinder wo...
