摘要
介绍了液压系统爬行问题,运用振动学原理描述了爬行产生的实质,着重分析了摩擦自激振动产生爬行的机理,给出了速度图和负载图,建立了动力学模型和数学表达式,并求解微分方程,最后提出了抑制爬行的主要措施。
The paper introduces a problem of creep in hydraulic system.Describe the substance produced by using ot vibration principle, especially anlayzes the creep reason of the frictional self-excited vibration (F.S.E.V) by using velocity chart and load chart. A dynamic model and mathematic expression are established, and the differential equation are solved.Finally puts forward a measure to control creep.
