【摘要】 本文针对一种参数可变液压蓄能器样机(其充气压力、充气体积、工作介质阻尼系数及进油口结构参数能够根据液压系统工况变化实时调整),采用磁流变液作为其主要工作介质之一,通过磁流变液工作腔实时调整样机的阻尼系数,以满足不同液压系统动态特性要求。重点研究磁流变液工作腔的结构及其外加电磁线圈磁路,在此基础上建立该部分数学模型,并将其与参数可变蓄能器样机整体数学模型结合进行理论分析,最后通过实验研究验证结构设计及理论分析的正确性。更多还原

【Abstract】 According to a variable parameters hydraulic accumulator prototype(its inflation pressure,inflatable volume,the damping coefficient of the working fluid and the inlet structure parameters of the hydraulic system operating conditions can be changed according to real-time adjustments),this paper uses magneto-rheological fluid as part of its main working medium,through the work of magneto-rheological fluid damping chamber prototype real-time adjustments to satisfy the requirements of different dynamic characteristics of hydraulic systems.The study focus on the magneto-rheological fluid cavity structure and its external electromagnetic coil magnetic circuit.The mathematical model of is set up on this basis,by combing the whole model of variable parameters hydraulic accumulator prototype,to make theoretical analysis.Finally prove that the structure design and theoretical analysis are correct.更多还原
