摘要(Abstract):

经市场反馈,旋挖钻机上所装多余流量阀发生异响,特别是在低档位工作时,多余流量阀发出高频振动响声,本文结合系统原理,利用AMESim软件对系统建立了局部模型,并仿真,从原理上解释了异响的原因,并给出改进措施,试验证明分析的结论是正确的,改进措施是可行的。
Feedback from the market,the excess flow valve in Rotary Drilling Rig knocking abnormally sometimes,especially the engine of the Rig working with lower speed.In this thesis the hydraulic system model of the excess flow valve was established and simulated by AMESim,The mechanism of the abnormal-knocking was illustrated and the improvements were advised in the end of the thesis.
