| 摘 要： | 摩托车舒适性受车速影响较大。本研究在考虑轮距滤波影响下,分析了摩托车上任一点加速度响应与频率和车速之间的关系;通过大量典型路面行驶车速试验,得到了水泥路和碎石路行驶车速数据,并进行了统计分析,发现行驶车速近似服从贝塔(Beta)分布;运用优化的直接法对贝塔(Beta)分布形状参数进行了估计,得到了摩托车在水泥路和碎石路上行驶时的具体分布规律,为全面设计和评价摩托车振动舒适性提供了依据。

| Abstract: | Speed has an important effect on motorcycle ride comfort. With wheelbase filter taking into consid- eration, the relationship between acceleration response and frequency and speed was analyzed. Through plenty of drive speed experiments, the datum of speed when motorcycle ran on gravel and concrete road were obtained and calculated. The result showed that the motorcycle speeds on typical road approximately obey Beta distribu- tion. At last, the shape parameters of Beta distribution were fit, and the detailed distribution of motorcycle speed on gravel and concrete road was developed, which provided evidence for the design and assessment of motorcycle ride comfort. |
