摘要
根据对称阀控非对称液压缸的特性,重新定义了负载压力和负载流量,推导出同时适用于对称阀控非对称液压缸和对称阀控对称液压缸的数学模型,为对称阀控液压缸系统的稳态和动态特性分析及液压控制回路的创建提供了理论依据。
Based on the feature of asymmetric hydraulic cylinder controlled by symmetric valve,the paper re-defines the load pressure and the load flow,derives the mathematical model that is suitable for both asymmetric and symmetric hydraulic cylinders controlled by symmetric valve,providing theoretical basis for the steady and dynamic state characteristic analysis of hydraulic cylinder system controlled by symmetric valve and the building of hydraulic control circuit.
