Article Preview

The mechanism and producing condition of instsbility in low velocity of hydraulic clinder was analyzed based on dynamic model and test ,Nonlinear coupled force combined with hydraulic spring and Self-excited vibration were though the key factor that could effect instability in low angular velocity, The mathematic model was established to obtain the change rule of speed & instantaneous acceleration of the hydraulic clinder A simulation analysisis then created for dynamic characteristics of hydraulic clinder with Simulink to analyze the effect of friction torque, leakage and compressibility of oil and liquid on low-speed stability of hydraulic motor, The test shows that fluctuation was the negative characteristics of friction in the self-excited vibration conditions .Some measures were proposed to improve the low-speed stability of hydraulic clinder.
