“爬行”是液压系统常见故障即液压执行元件低速运动时出现时断时续的速度不匀现象。“爬行”会影响工作稳定性和作业精度。(1)驱动刚性差引起的“爬行”
“Crawl” is a common failure of the hydraulic system that hydraulic actuator low-speed movement appears intermittent when the speed of uneven phenomenon. Crawling can affect job stability and job accuracy. (1) driven by poor rigidity caused by “crawling”
