冷滚轧机床液压传动系统的动态特性分析

Dynamic analysis of cold roll forming machine's hydraulic system

对冷滚轧机床液压系统进行了动态分析。对系统中的调速阀、溢流阀、泵及出口管路、液压缸等分别进行了分析,建立了系统模型,并在此基础上应用软件进行系统仿真。根据仿真结果对系统进行了改进,提出了满足其工作性能要求的设计方法,改善了系统的动态特性。

In this dissertation dynamic analysis of a cold roll forming machine's hydraulic system is conducted. The system model and block diagram are obtained by analyses of flow control valve, relief valve, pump with outletpipe and hydraulic cylinder. The system is simulated using software, the simulation results are used in the improvements of system properties and the design method settling for work performance is broughtforward.
