英文摘要	通过动力学模型和试验,分析了液压马达低速波动的机理和产生条件,认为非线性液压弹簧力和非线性摩擦力的耦合作用是液压马达低速波动主要原因;通过试验研究了非线性摩擦扭矩、泄漏系数、粘性阻尼系数、油液压缩系数等因素对液压马达低速波动的影响,揭示出液压马达低速波动是在负特性摩擦阻力工况下的自激振动现象,并提出了改善液压马达低速稳定性的措施。; The mechanism and the producing condition of instability in low velocity of hydraulic motors were analyzed based on dynamic model and test.Nonlinear coupled force combined with hydraulic spring and self-excited vibration was thought to be the key factor that could affect instability in low angular velocity.The results indicated that the low speed creeping characteristics of hydraulic motor could be affected by friction torque,leakage and compressibility of oil and liquid.The test showed that the 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 motors.; 国家高技术研究发展计划(863计划)资助项目(2008AA042501);福建省自然科学基金资助项目(2009J01259);福建省教育厅资助项目(JB08182)
