在引入新的负载流量和负载压力定义的基础上，详细地分析了非对称阀控非对称缸系统的静动态特性，证明了阀控非对称缸的动态特性在两个方向是不同的，且在分析非对称缸的性能时，阔的负载流量和负载压力必须重新定义，所得的结论表明，只要改变其中的有关参数，即可应用于其它阀控缸系统，具有通用性。 Based on the introduction of new definition of load flow and load pressure, the static and dynamic characteristics of asymmetric valve-controlled asymmetric cylinder system are analyzed in detail. It is proved that the dynamic characteristics of valve-controlled asymmetric cylinder are different in both directions In analyzing the performance of asymmetric cylinders, the wide load flow and load pressure must be redefined. The conclusions obtained show that it can be applied to other valve-controlled cylinder systems with commonality as long as the relevant parameters are changed.
