以挖掘机工作臂液压系统的数控化改造为例,介绍了液压系统数字执行元件的结构原理和计算机控制技术,简述应用计算机控制技术把原来的液压伺服系统进行数控化改造的基本工作原理,为分析现代化液压系统或进行老液压系统的数控化改造提供了有价值的参考。
Taking the numerical control transformation of the hydraulic system of excavator working arm as an example, the structural principle and computer control technology of the digital actuator of the hydraulic system are introduced. The basic working principle of using the computer control technology to digitally transform the original hydraulic servo system is briefly described. It provides a valuable reference for the analysis of modern hydraulic system or the numerical control of the old hydraulic system.
