摘要
本文根据随机振动理论建立了自行车行驶系统动力学模型。按ISO2631推荐的车辆行驶平顺性的评价方法,以载重车为例进行分析计算,绘出人体所受的垂直加速度响应曲线。结果表明,有效的减轻载重车的振动是十分必要的。
In this paper, based on the theory of randomvibration, a bysical model of ride vibration has been presented. According to the evaluation method of ISO2631, the virtical response acceleration of a bysical seat has been calculated and then the curves have been plotted. From the results of above analysis, we can come to conclusion that it is necessary to improve ride comfort for the bysical rider.
