With the function of providing energy,eliminating fluctuation,absorbing hydraulic pulsation and recovering energy,accumulator plays an important rolein the hydraulic system.With the constant development of hydraulic technology,engineering equipment with overloading and mass flow emerges in endlessly,and the demand of large capacity of the accumulator is increasing.However,the difficulties in manufacturing of this kind of accumulator,large inertia and reaction insensitive also restrict its development.Engineering usually uses the accumulator group instead of a single large capacity of the accumulator.How to correctly choose the accumulator group and take full advantage of itneed to be solved.This article mainly discusses the theory analysis of accumulator group,which consists of small volume of accumulator,establishes relevant mathematical model,analysis the dynamic character of the accumulator group using the software of AMESim.Under the premise of the load in different frequency,study its ability of oil suppling and resisting line pressure fluctuations.This research will provide help for selecting suitable accumulator group in the future.
