| 摘 要： | 以汽车二自由度悬架系统为研究对象,针对半主动悬架系统,提出以车身加速度为控制目的的模糊控制策略。以白噪声随机响应谱作为B级路面的激励输入,对被动悬架和半主动悬架系统进行仿真研究。仿真后的被动悬架与半主动悬架对结果表明,所提出的模糊控制策略有效的降低了悬架系统被击穿的可能性,提高了汽车乘坐的舒适性。

| Abstract: | Taken 2-DOF model of vehicle suspension system as the object of study, the fuzzy control strategies to deal with acceleration ofvehilce boday for semi-active suspension system were presented in this paper. The excitation input of B level grade road was provided by white-noise response sprectrum signal and the simulation of passive suspension system and semi-active suspension system was conducted. The test results can be described that the newly suggested fuzzy control strategies decreased the probability of suspension thus to improve the ride comfort. |
