Problems solved by technology
[0004] In the automotive system, the plunger pump is used as the power source for the coupling of the clutch hub. If there is a fluctuation in the output pressure during use, the coupling state of the clutch hub will be unstable, resulting in unstable power transmission, and eventually the vehicle body will shake. NVH problems such as movement and noise

Description
technical field [0001] The present application relates to the field of pressure fluctuation testing, in particular to a pressure fluctuation testing device for a hydraulic drive system. Background technique [0002] The hydraulic drive system uses hydraulic oil as the working medium, and uses the pressure of the hydraulic oil to transmit power. [0003] Piston pump is an important device of hydraulic drive system. It relies on the reciprocating movement of the plunger in the cylinder to change the volume of the sealed working chamber to realize oil absorption and oil pressure. The plunger pump has the advantages of high rated pressure, compact structure, high efficiency and convenient flow adjustment, and is widely used in high pressure, large flow and flow adjustment occasions, such as hydraulic presses, engineering machinery and ships. [0004] In the automotive system, the plunger pump is used as the power source for the coupling of the clutch hub. If there is a fluctua...
