摘要 提出一种新型液压变压器配流副结构以扩展其输出压力,建立了恒压网络实验系统以测试液压变压器的性能.通过仿真和实验研究来探讨液压变压器的输出压力、排量特性及速度稳定性.研究结果表明:所设计的液压变压器能够实现压力调节功能,输出压力由配流盘控制角度决定同时受负载的影响,负载压力与油源压力之比的变化范围大致为0~1.2.液压变压器是一个变排量液压元件,排量由配流盘的控制角度决定,而不受负载的影响.液压变压器的速度稳定性随着配流盘控制角度的增加而提高,当配流盘控制角度小于15°时,液压变压器存在运动死区.液压变压器的高瞬时驱动扭矩波动是其速度稳定性差的主要原因.研究结果将有助于进一步提高液压变压器的性能.
