汽车空气悬架-转向机构的运动学分析及优化

Kinematics analysis and structure parameter optimization of air suspension steering framework for automobile

利用虚拟样机技术建立了某种型号汽车的包括转向机构在内的空气悬架-转向系统的多体运动学计算模型,并进行了运动学分析研究.建立了以转向轮接地点的侧向滑移量最小为目标函数的结构参数优化设计模型,并进行了优化分析,得到了空气悬架-转向系统结构参数的较为合理的优化设计方案,为该型汽车悬架系统的进一步改进提供了理论依据.

The muIti - body kinematics model of an air suspension steering system for some kind of great passenger cars is established by a virtual prototyping technique in the software ADAMS, and the kinematics analysis is carried out. Based on this, the structure optimal design model is established by considering the side way displacement of the wheel＇s contacting ground point as the goal of the function, and optimization is performed. Finally, a relatively reasonable project for the air suspension steering system is obtained.
