Abstract  A high-order curve was proposed for the stator profile in order to address the flow leakage limitation of the internal curve type water hydraulic motor. Then flow leakage models for piston pair and distribution pair were established, respectively. The friction pair parameters were optimized using minimum total power loss as objective function based on the leakage models. The displacement performance of motor was experimentally investigated under different load conditions. The test results agreed well with the calculated values under various load conditions. The error rate of test was restricted within 5%. The flow characteristic was improved effectively and the volumetric efficiency reached a maximum of 94.71% at no-load state. Research indicates that the piston-liner clearance is the most critical factor determining the leakage flow, followed by the end clearance of port plate and rotor.

内曲线式端面配流水液压马达的优化设计

针对内曲线式端面配流水液压马达工作存在的流量泄漏问题,改进定子轮廓曲线方程并建立马达关键摩擦副的泄漏模型,以总功率损失最小为目标函数，对摩擦面间隙进行优化设计.搭建水液压马达测试平台进行不同负载下的马达排量测试.试验结果表明：不同负载条件下流量模型均能较好反映马达输出流量随转速上升的变化情况,试验的真实误差率低于5%.水液压马达的流量特性得到明显改善,空载下的水液压马达容积效率最高可提升至94.71%.研究表明：柱塞与转子缸孔的间隙值是影响水液压马达泄漏流量的最主要参数,其次是配流体与转子体的端面间隙值.
