【摘要】 随着城市轻轨交通的飞速发展,噪声污染越来越成为公众关注的敏感问题,本文对弹性车轮的减噪特性进行了研究,从频响函数的角度对弹性车轮和刚性车轮的振动特性进行了比较;通过对承剪型橡胶弹性车轮和刚性车轮进行噪声对比试验,验证了弹性车轮在降低轮轨噪声总量。缩短噪声衰减时间和改善噪声频谱特性方面的优良性能。更多还原

【Abstract】 ： With the rapid development of urban light rail transit, wheel/rail noise pollu- tion has become a sensitive topic of citizens. In this paper, the mechanism of resilient wheels in how to eliminate the wheel/rail noise was studied. From the point of Frequency Response Functions,the vibration properties of resilient and solid wheels are compared. The effectivity of resilient wheels in decreasing the amount of wheel/rail noise。shortening the decline time and improving the noise spectrum was sufficiently proved through the acoustical experiment between a practical rubber cushioned wheel and a solid wheel.更多还原
