摘要
本文通过汽车沿不平路面行驶时所激起的垂直振动分析,提出了汽车行驶极限速度的评价指标;通过悬架和轮胎对极限速度评价指标影响的分析,从系统优化设计观点,提出了汽车在给定行驶条件下悬架和轮胎的刚度和阻尼最佳匹配方法,以提高汽车行驶极限速度。
The vehicle vibration of Beijing jeep excited by road surtace Roughness is analysed in this papar. The overall criteria to determine the limiting speed of the vehicle travelling on uneven road are proposed. The effects of the parameters of suspension and tyre on above mentioned criteria are analysed. From the view of designing an optimal system, this method will math stiffness and damping of suspension with tyre to increase the limiting speed of vehicle on uneven road.
