| 摘 要： | 通过仿真分析,研究液压滑阀阀芯在不开均压槽、开3条矩形槽、开5条矩形槽、开5条三角形槽4种情况下,阀芯歪斜时阀芯卡紧力的变化。由仿真结果可知:阀芯歪斜时,在阀芯上开均压槽可以有效减小卡紧力,开的均压槽越多,卡紧力越小;开相同数量的矩形槽比三角槽的卡紧力大,但是更利于使阀芯趋于同心。

| Abstract: | Through simulation and analysis,the changes in clamping force of the hydraulic slide-valve spool when the spool skewed were studied,with no pressure-equalizing grooves,three rectangular grooves,five rectangular grooves and five triangular grooves.The simulation results show:opening pressure-equalizing grooves in the valve can reduce clamping force;the more pressure-equalizing grooves open,the smaller the clamping force becomes.With the same amount,clamping force of spool with rectangular grooves is larger t... |
