| 水力机械的传递特性能够表达自身的水力性能以及与之相关的机械性能。所叙述的水泵传递特性理论与实验研究，传递系统除水压和流量特性之外，还包含了水泵转轴的转动力矩和转动速度特性，从而较为完整地表现包含水力与动力两方面的水泵总体特性。分析计算和实验研究的结果表明，数据处理、传递系数辩识方式以及实验方法是可行的；泵轴的转动特性影响传递矩阵的系数数值，但波动参数之间的基本特性关系保持不变；较为完整的矩阵表达传达了水泵水力和转动特性及其相互关系的一些新信
息。研究的基本结论为全面、深入了解水泵的系统特性提供了重要的依据。 |
| 英文摘要: |
| The transmission characteristics of hydraulic machines illustrate the hydraulic features and machinery performances. The matrix representation for pump transmission characteristics was well understood in steady oscilliation, but less understood for flow pressure and flow rate of a hydraulic circuit. The author presented a theoretical and experimental study on pump transmission characteristics of a system including a rotation system of shaft as well as hydraulic circuit. The results of experiment and computation show that: the data processing, parameter identification and testing principle are feasible; the rotation system characteristics will not change the primary relationships among the fluctuation parameters though they influence the values of matrix coefficients; the repesentation of the transfer matrix would show some useful information of pump characteristics. |
