摘要
空气悬架系统具有寿命长、自振频率低、刚度与高度可调等优点,广泛应用于野外作业车辆。但现有空气悬架系统存在控制模式单一、参数解耦困难、非线性与时滞性严重等问题,直接限制了车辆行驶安全性、舒适性和通过性的提升。通过对世界范围内当前在悬架系统参数模型构建、汽车空气悬架系统以及空气悬架控制技术等不同角度着手的研究情况进行分析,同时提到目前我国在汽车空气悬架系统及精准控制技术方面现存问题和未来发展趋势,为我国空气悬架高精度控制技术的发展提供参考。
The air suspension system has the advantages of long service life,low self-vibration frequency,adjustable stiffness and height,and is widely used in field vehicles.However,the existing suspension system has problems such as single control mode,difficult parameter decoupling,nonlinearity and serious time delay,which directly limits the improvement of vehicle safety,comfort and passability.This paper analyzes the current research situation in vehicle air suspension system,suspension system parameter modeling and air suspension control technology at home and abroad,and points out the existing problems and future development trends in automobile air suspension system and precision control technology in China,which provides a reference for the development of high-precision control technology of air suspension in China.
