在液压传动装置中,常常出现振荡。振荡现象大多可归结为弹簧-质量系统的作用。此时,处在压力下的油液容积相当于弹簧;而油马达、油缸及其连接的负载相当于质量。振荡由于电容性振子(弹簧)和电感性振子(质量)之间发生能量交换而引起。在用阀和泵进行压力调节时,也会产生振荡现象,但是这种现象并不是弹簧-质量作用的结果。 In hydraulic actuators, oscillations often occur. Most oscillations can be attributed to the spring-mass system’s role. At this point, the volume of oil under pressure is equivalent to the spring; and the load on the oil motor, fuel tank and its connection is equivalent to mass. Oscillation is caused by the exchange of energy between the capacitive vibrator (spring) and the inductive vibrator (mass). Oscillations can also occur when valves and pumps are pressure-regulated, but this is not the result of spring-mass effects.
