摘要
基于功率键合原理,把液腔和气腔分别视为容性元和惯性元,建立了囊式蓄能器功率键合图及数学模型,在Matlab/Simulink平台上实现了囊式蓄能器仿真模型,模拟了蓄能器对压力冲击的抑制作用。研究了在额定压力下蓄能器容积对系统压力超调值的影响,结果表明,蓄能器容积越大,系统压力超调值越小。给出了规定系统压力下蓄能器容积参数的选择建议。
With the liquid-filled and air-filled cavity of accumulator being regarded as compatible and inertial elements, bond graph of Peltry energy accumulator and its mathematic model are built based on the power bond theory. The simulation model of Peltry energy accumulator has been realized on the platform of matlab/simulink, simulating the inhibitory effect of accumulator on the pressure impact. The study on the influence of the accumulator volume on the overshoot of system pressure shows that the larger accumulator volume makes pressure overshoot smaller. Then a suggestion is given for the selection of the accumulator volume under fixed system pressure.
