基于独立调节高度和刚度的空气悬架优化和分析

悬架因着力解决车辆所需的平顺性和操纵性而扮演了重要的角色。传统的空气悬架系统通过气囊的不断膨胀来控制高度,然而这种悬架的刚度不能被控制。因此,提出一种允许行驶高度和悬架刚度调节的悬架系统。此系统可以根据不同的路况来改变行驶高度和悬架刚度;它允许车辆的固有频率和高度根据路况和负载而调整。研究了空气悬架的行驶高度和刚度调节的优化问题进而提出了优化设计方案并验证了该系统的数学建模优点。

Analysis and Optimization of Air Suspension System with Independent Height and Stiffness Tuning

Suspensions play a crucial role for comfort and handing of vehicles. The conventional air suspension systems chassis height can be controlled by further inflating the airbag, however, the suspension stiffness is not controllable. Therefore, a new air suspension allowing independent ride height and stiffness tuning was developed. In this air suspension system, the stiffness and ride height of the vehicle could be simultaneously altered for different driving conditions;the vehicle' s natural frequency and height could be adjusted according to load and road conditions. The optimization of the air suspension design with ride height and stiffness tuning was discussed, the optimum design of the new air suspension system was developed and the advantages of the new air suspension system were shown.
