【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),采用阀控非对称缸系统实现气体参数在线调整装置,并采用"PC+DSP(Digtal Signal Processor)"建立其两级计算机控制系统。文中重点针对该气体参数在线调整装置,建立其数学模型,并对其进行仿真分析和实验研究。更多还原

【Abstract】 Aimed to a kind of self-parameters adjusted accumulator prototype(its inflation pressure,inflation volume,working oil damping factor and inlet structural parameters could be adjusted real-timely according to working conditions),controlled asymmetric cylinder is used on the online regulator of air chamber parameters,and two-level computer control system between PC and DSP is designed.It is impotant that Mathematical Modeling,simulation analysis and experimentation study are described for the online regulator of air chamber parameters in the paper.更多还原
