Research of Hydraulic Accumulator in Secondary Regulated Loading System

The mathematical model of secondary regulated loading system with accumulator was established.The influence of accumulation on pressure pulsation of constant pressure in the secondary regulated loading system was investigated through theoretical and simulated analysis.The matching method of accumulator was obtained.The suggestion was presented to select corresponding accumulators based on the different subsystems in the constant pressure system.The influence of pressure pulsation on the precision loading was reduced by setup accumulator at the high and low ports.
