摘　　要：基于连续采煤机液驱行走的需求,设计了液驱行走负载敏感液压系统,分析了负载敏感液压系统压力脉动作用机理,研究了负载反馈回路2种滤波方法,设计了变阻尼阀,并在连续采煤机液驱行走负载敏感液压系统进行了试验,试验结果表明,通过调节变阻尼阀可达到预期的稳定性。Based on the demand for continuous miner hydraulic drive walking,a load sensitive hydraulic system for hydraulic drive walking was designed.The action mechanism of pressure pulsation in the load sensitive hydraulic system was analyzed,and two filtering methods for load feedback loop were studied.A variable damping valve was designed and tested on the load sensitive hydraulic system of continuous miner hydraulic drive walking.The test results showed that the expected stability can be achieved by adjusting the variable damping valve.
