| 摘 要： | 基于多项式判别理论研究车辆时滞半主动悬架系统失稳机理，得出了悬架系统的失稳条件及其失稳临界时滞，为半主动悬架系统时滞控制研究提供了依据。应用数值仿真的方法分析时滞对悬架系统稳定性的影响，并在自行研制的1：1物理模型半主动悬架试验系统上进行了台架试验。结果表明，基于多项式理论研究时滞半主动悬架稳定性的方法简单，得出的稳定性条件可靠，为半主动悬架及其控制系统设计和分析奠定了基础。

| Abstract: | Based on the polynomial differentiate theory, the lost stability principium of the vehicle semi-active suspension with time delay was studied. The condition of the system control with time delay and the critical time delay were obtained. It is the gist for the study of semi-active suspention with time delay. The time delay influence on the system was analysed by numerical simulation and the bench test was done. The results show that the study of stability of semi-active suspension with time delay is very easy and the conclusion is credible. It will be the foundation of semi-active suspension system design and analysis. |
