摘要
为研究蓄能器吸收液压冲击的作用,应用AMESim仿真分析平台,建立带蓄能器的100 m长等径直管液压系统模型,对接入蓄能器前的直接和间接液压冲击进行理论计算和仿真分析,结果一致,验证了仿真模型的正确性。为消除直接液压冲击,理论计算得到所需蓄能器的最小容积,对接入蓄能器后的直接液压冲击仿真分析表明,计算所得蓄能器容积过小,液压冲击吸收效果并不明显,由此得到蓄能器容积的最优值。
In order to study the pressure pulsation absorbing of hydraulic accumulator, a hydraulic system with 100 m straight pipelines of the same diameter is established in AMESim.Both direct and indirect pressure pulsation are calculated theo-retically and simulated in the system without accumulator, the results are almost the same and prove the validity of the simulation model.To absorb the direct pressure pulsation, minimal volume of the accumulator is calculated theoretically, and simulated in the system with accumulator, which shows that the volume is too small to absorb the pulsation effectively.The optimized volume of the accumulator is achieved through simulation.
