| Abstract: | In order to improve the maneuverability of operational devices on off-highway vehicles,the traditional multi-way directional valve with electro-hydraulic proportional control was remodeled digitally.A digital high-speed on-off valve was substituted for the traditional electrohydraulic proportional reducing valve as pressure-pilot control part.The pulse width modulation(PWM) control strategy for directly controlling this fast digital on-off valve was investigated and analyzed.The validity and feasibility of the remodeling principle was verified,the reliability of the hydraulic system of the operational devices on off-highway vehicles improved,and the anti-interference capability of the system increased. |
| Keywords: | digital multi-way directional valve high-speed digital on-off valve PWM |
