摘要
阐述了流量放大液压转向系统的工作原理,建立了流量放大系统的动态数学模型,并利用计算机进行动态仿真。仿真模型采用参数化建模。针对结构参数中对系统性能影响较大、且难以计量的阻尼系数进行专门研究,仿真出阻尼为不同值时的系统动态响应结果。
The principle behind the flow amplifier steering system is described and a dynamic mathematical model is established. On this basis, the simulation model is constructed on a computer in which the value of parameter is easily modified. Because the damping is an important factor to dynamic characters but also is difficultly to measure, the particular study is doing on the subject of how damping factors influence the system characters. The response curves are simulated corresponding to various damping values.
