摘要
从研究直辐刚性车轮频谱特性入手 ,在线测量了地铁轮轨噪声 ,开发了一种承剪型弹性车轮 ,并对该车轮的噪声特性进行了实验室测量。结果表明 :承剪型弹性车轮能降低轮轨噪声 。
This paper begins with the research on the frequency spectrum features of rigid wheels with straight spoke, the metro wheel rail noise is measured on track, a kind of sheared resilient wheels is developed, and the noise features of the wheel are measured in laboratory. The results show that the sheared resilient wheels can reduce the wheel rail noise. Reference is made for development of urban vehicles with low noise.
