Hydraulic accumulator algorithm

Contrary to a traditional accumulator, the new accumulator is designed as a split type accumulator with one fluid cavity and two gas cavities. The hydraulic fluid cavity and the gas cavity are separated which means the fluid pressure can be different from the gas pressure. As illustrated in Fig. 1, all three cavities are fixed on the.
