Abstract
In some special application fields,the output pressure of water hydraulic system is variable.Some accumulators were installed near the outlet of water pump to absorb pressure pulsation on the working condition of different output pressure.The mathematic model on absorbing pressure pulsation for accumulator group was set up,the characteristic on absorbing pressure pulsation for accumulator group with different gas pressure was discussed by the correlative simulation software.Corresponding test was done.The results of simulation and test provide reference for the reduction of vibration and noise of varying pressure water hydraulic system.
