| 摘 要： | 对液压变压器工作于四象限的特性进行了研究,建立了液压变压器四象限工作的动力学模型.对液压变压器四象限工况下,液压蓄能器流量特性、液压恒压网络系统压力特性以及液压变压器控制角特性进行了仿真研究,结果表明:随着负载的变化,液压恒压网络系统压力波动范围不超过3%,基本保持为准液压恒压网络系统,而液压蓄能器的流量以及液压变压器的控制角则呈非线性增加或减小.

| Abstract: | By studying the four-quadrants operation characteristic of hydraulic transformer,a dynamics model was built.The flow characteristic of hydraulic accumulator,the pressure characteristics of hydraulic constant pressure rail system and the control angel of hydraulic transformer were simulated.Results show that the pressure variation of hydraulic constant pressure rail system is not more than 3 percent and keeps at a nominal level.The flow of hydraulic accumulator and the control angle of the hydraulic transformer change with the load variation. |
