离合器控制系统比例压力控制阀特性研究
发布时间:2022-01-06 08:50
比例压力控制阀作为控制元件应用于液压系统,并对这些系统的性能产生重要影响。比例压力控制阀保持压力恒定,操控离合器控制系统。然而,由于电,磁,液压,机械之间高度耦合、相互影响,使其表现出复杂的特性。并且,大部分复杂特性都是由于这些元素的非线性造成的。在设计这些时,研究其静态动态特性不失为改进其性能的一种可行的方法研究表明,比例压力控制阀的特性与油源流量、滑阀重叠量、弹簧刚度、阻尼系数、负载和控制器性能都有关。本研究旨在设计两级比例压力控制阀,并研究其特性;分析阀芯尺寸、容腔大小、阻尼孔等设计参数,对该阀静态、动态特性的影响;最终运用此阀操纵离合器控制系统。对该比例压力控制阀的控制性能进行分析也很重要,因为能更好的理解这些元素导致的,系统可能会出现的问题。对这些元素的控制不善,会影响系统的效率。比例压力控制阀应用于需要快速性和准确性的场合。不善的控制会影响系统的响应及稳定,给用户带来不适,会对系统造成破坏,也增加了油耗。Matlab/Simulink是一个物理仿真工具,用来预测系统的物理行为,本研究利用其对阀进行仿真建模,分析阶跃响应,研究阀的性能。通过深入研究先导阀、主阀、离合器液压缸的...
