The accumulator is a special container which used for accumulate energy and its responsiveness plays an important role in improving hydraulic system performance. Therefore, it can be seen from the current research results that most scholars focus on the bladder-type accumulator owing to the reflection of the bladder-type accumulator is fast. The hydraulic system with a bladder-type accumulator is adapted to absorb shock pressure and eliminate pressure pulsations. However, due to the sudden change of the reversing valve or the sudden stop of the actuator, the pressure shock will occur in the hydraulic system, and the relief valve will not be able to move, which will cause the pipeline to vibrate. In severe cases, the hydraulic pipe will be broken and caused a safety accident. In actual use, the effect of absorbing pressure shock is not ideal due to improper selection of accumulator parameters. Therefore, the main objective of this study is to use theoretical analysis, computer simulation and experimental research to analyse the influence of accumulator parameters on the hydraulic system.
