根据车辆液压驱动系统的需要,从提高系统工作性能,补偿恒压泵的动态误差、负荷波动产生的压力波动与冲击的角度考虑蓄能器的参数配置方法,并分析其数学模型,得出蓄能器组的固有频率应着重分布在0.2￣3Hz以内,构成一个对区间变化压力均有良好吸收能力的可调式蓄能装置,或用一组充气压力不同的蓄能器与系统匹配,达到对不同压力区间动态波动压力良好吸收的目的。
According to the requirement of hydraulic drive system of vehicle, the parameter configuration method of accumulator is considered in terms of improving system performance, compensating the dynamic error of constant pressure pump, pressure fluctuation and impact caused by load fluctuation, and analyzing the mathematical model, The natural frequency of the transducer group should be redistributed within 0.2 ~ 3Hz to form an adjustable energy storage device with good absorption capacity for changing the interval pressure or to match with a system of accumulators with different inflation pressures Different pressure range of dynamic fluctuations in the pressure of good absorption purposes.
