摘要

本文采用模态控制方法对四分之一汽车模型的主动悬架进行控制。模态控制可以设计成在不干扰其余模态的情况下改变系统任何模态的动力学。因此,在本研究中,使用模态控制来改变四分之一汽车悬架模型的车身弹跳模式的复特征值,从而通过优化从道路扰动到簧载和非簧载质量位移的频率响应函数,提高车辆的乘坐舒适性。已经证明,模态控制可以直接用于改变车辆悬架的动力学,即软悬架,硬悬架,这取决于驾驶员的态度,影响车辆的稳定性和道路条件,即城市驾驶,越野驾驶。

Improving Ride-Comfort of a Quarter-Car Model using Modal Control
In this paper, modal control was used to control the active suspension of a quarter-car model. Modal control can be designed to alter the dynamics of any mode of a system without disturbing the remaining modes. Therefore, in this study, modal control was used to alter the complex eigenvalue of the body-bounce mode of a quarter-car suspension model and thereby by optimizing a measure of the frequency response functions from road disturbance to sprung and unsprung mass displacements, the ride-comfort of a vehicle was improved. It has been shown that modal control can be used in a direct manner to change the dynamics of a vehicle suspension i.e. soft suspension, stiff suspension depending on the driver attitude that affects the vehicle stability and road conditions i.e. urban driving, off-road driving.
