Simulation Analysis of Pressure Pulsation and Absorbing for Long Hydraulic Pipeline with AMESim

In order to study the pressure pulsation absorbing of hydraulic accumulator,a hydraulic system with 100 m straight pipelines of the same diameter is established in AMESim. Both direct and indirect pressure pulsation are calculated theoretically and simulated in the system without accumulator,the results are almost the same and prove the validity of the simulation model. To absorb the direct pressure pulsation,minimal volume of the accumulator is calculated theoretically,and simulated in the system with accumulator,which shows that the volume is too small to absorb the pulsation effectively. The optimized volume of the accumulator is achieved through simulation.
