Abstract: Describing the structure of fluid system on a solenoid valve test bed, the mechanism which induces the fluid pulsation and the damages to the normal operation of the test bed were discussed to reveal the necessity to explain the reasons why the fluid pulsation should be investigated and reduced by some technical measures to take. A group of accumulators was applied to the fluid system on solenoid valve test bed so as to reduce the fluid pulsation, with the construction and working principle of accumulator described. Furthermore, the effect of pressure of the fluid system in combination with accumulators on the amplitude-frequency characteristics of pumped flow pulsation and its dynamic behavior were investigated via simulation. Then, the related parameters were chosen rationally to optimize the reduction of the fluid pulsation.
