Abstract

Abstract:

A relation between motorcycle response and speed was analyzed herein, then through lots of tests, the statistic distributions of speed when motorcycle ran on gravel and concrete road were developed. And a new evaluation method of motorcycle ride comfort based on speed and frequency weighting was put forward, and the ride comfort of selected 125 motorcycle was tested and evaluated. The results show that speed and frequency weighting RMS of acceleration is the synthetically reflection to frequency weighting RMS of acceleration at different speeds, which has universality and practical value.

Key words: motorcycle ride comfort, speed, frequency, weighting, evaluation

摘要：

考虑轮距滤波的情况下，分析了摩托车振动响应与车速之间的关系，并通过大量试验找出了摩托车在碎石路和水泥路上行驶时车速的统计规律。在此基础上，提出了基于速度与频率加权的摩托车舒适性客观评价方法，并对某125摩托车进行了舒适性试验和评价。结果表明，速度和频率加权加速度均方根值是各种车速下频率加权加速度均方根值的综合反映，具有较强的通用性和实用价值。
