摘要
本文提出了一个柱塞泵柱塞腔压力瞬变过程的理论模型.该模型中引入了液阻、液感、液容,以及经辨识而得的随压力变化的体积弹性模量和变化的流量系数.对于不同的负载工况、不同的配油盘结构,模型仿真结果均能很好地与实测结果相吻合.
An analytical model of pressure transients inside the piston pump cyli-nder has been developed,which includes resistance,inductance and capacitancewith art identified pressure-dependent bulk modulus and a variable flow coefficient.Simulation results agreed quite well with those from the measurements of differentpump loads and portplate configurations.
