【 摘 要 】

In order to meet the driving and mobility requirements of a wheel drive hydraulic hybrid vehicle, the mathematical model of the airbag type accumulator was established, and its basic working parameters were determined initially. The accumulator's individual drive variable motor/pump test was carried out by using the test bench. The experiment was conducted by using the orthogonal experimental design method. The rationality of the accumulator operating parameters was verified. The rational voltage value adjustment range was determined. It was shown that the effect of the load on the acceleration performance of the variable motor/pump was greater than that of the accumulator working pressure. Furthermore, the measures and methods for improving the acceleration performance of the variable motor/pump were obtained.
