摘要：The hydraulic muffler is a component in the hydraulic system, its intrinsic vibration frequency and the main anti resonance frequency are closely related to the structure parameters of the mufflers. When the structure parameters remain unchanged, main anti resonance frequency is deviated from the fluctuation frequency of the system, so the attenuation effect is reduced rapidly. Therefore, it is particularly important to design a hydraulic muffler with special structural parameters that can be changed in time with pulsating frequency of the system. This paper takes the H-hydraulic muffler as the research object, which changes the structure parameters of the muffler according to the speed of the pump, so as to achieve a relatively stable pulsation absorption effect.
