Research on the Efficiency of Bent Axis Hydraulic Piston Motor

针对工程机械能量回收系统的效率优化问题,建立了关键元件液压马达的机械效率、容积效率模型,借助试验方法和MATLAB中辨识函数等辨识得到各损耗参数,从液压马达排量、液压马达压力等方面研究了液压马达的效率特性。结果表明,理论分析曲线和试验曲线基本重合,可以为效率优化提供足够准确的信息。

To improve the efficiency of energy regeneration system applied in construction machinery, the efficiency mathematical model of the hydraulic motor is constructed. As some parameters of the motor are unknown, we test a rig and propose a measure method to identify the unknown parameters. At last, the characteristic of efficiency of the hydraulic motor is analyzed.
