HYDRAULIC SYSTEM AND METHOD OF ACTIVELY DAMPING OSCILLATIONS DURING OPERATION THEREOF |
摘要 |
A hydraulic system and a method of actively damping oscillations during actuation of a hydraulic cylinder in a hydraulic system is disclosed. The hydraulic cylinder is actuated by energizing a motor that rotatably drives a pump. The pump supplies a fluid to the hydraulic cylinder to actuate the cylinder. A pressure of the fluid is sensed during actuation of the hydraulic cylinder. A rotational speed of the motor is varied in response to the sensed pressure of the fluid. This varying of the rotational speed of the motor actively damps pressure oscillations during actuation of the hydraulic cylinder. |
