摘　　要：提出了一种新型专门用于角振动台的四叶片摆动液压马达的结构模型,该马达使用静压支承技术和间隙密封的形式,能够解决在高频振动工况下马达寿命低的问题。针对马达的静压轴承刚度、泄漏特性进行分析,证明其具有液压固有频率高、摩擦力矩小、寿命高、输出能力强等优点,说明该马达在液压角振动台的工况下有着良好的表现。The novel structure model of the 4-vane swing hydraulic motor,which is specifically applied on angular vibration table,is proposed in our study.Using the analogous hydrostatic bearing technique and clearance seal format,the motor will be able to solve the short life problem under the high frequency vibration condition.By analyzing the analogous hydrostatic bearing stiffness and leakage character,we prove that this motor has high bandwidth,low friction,long life,powerful output capability,which further testifies that this motor has an excellent performance on the condition of hydraulic angular vibration table.
