摘　　要：非对称液压缸两腔结构参数不同,给阀控非对称缸数学建模带来了较大的困难。文中针对现行阀控非对称液压缸数学模型及简化方法作了分析比较,提出了一种新的简化方法,并据此导出了较为精确的数学模型。The structural parameters of the two chambers of the asymmetric hydraulic cylinder are different,which brings great difficulties to the mathematical modeling of the valve-controlled asymmetric cylinder.This paper analyzes and compares the current mathematical models and simplified methods of valve-controlled asymmetric hydraulic cylinders,proposes a new simplified method,and derives a more accurate mathematical model based on this.
