在液压系统中,普遍存在着压力脉动现象,它主要是由于液压泵的流量脉动引起的,压力脉动将影响系统的正常工作,降低元件和管道的寿命,严重时甚至使液压系统无法工作。为此,最常见的解决办法是用蓄能器来吸收压力脉动。一般的囊式蓄能器其结构形式与系统的联结为并联武,如图1所示。经研究发现,该种蓄能器固有频率较低,用它 In the hydraulic system, there is a widespread pressure pulsation, which is mainly caused by the pulsation of the hydraulic pump. The pressure pulsation will affect the normal operation of the system, reduce the life of the components and pipes, and even make the hydraulic system unable to work in severe cases. For this reason, the most common solution is to use an accumulator to absorb pressure pulsations. The general structure of the capsule-type energy storage system and the link for the parallel weapons, as shown in Figure 1. The study found that the natural frequency of the accumulator is low, use it
