摘　　要：建立了旋转控制阀刃口结构为短切口的数学模型,并且就短切口转阀的特性进行了仿真研究。计算分析和仿真研究的结果表明:短切口结构的转阀可以有效地控制节流面积的变化速度,实现手动转向力到辅助液压力的平滑过渡。A mathematical model for the rotary valve of short cutting edge was established, and the simulation research for its characteristics was made. The results of calculation analysis and simulation research shows that the valve can control the area of metering orifices gradually, and change the assist pressure from manual to power - steering smoothly.
