频响函数在地铁弹性车轮上的应用

Development of Resilient Wheels on Frequency Function

根据固体振动噪声与固体振动速度的关系理论,用有限元法对承剪型弹性车轮进行模态分析,计算该车轮的速度频响函数。在与刚性车轮速度频响函数比较后,得到弹性车轮的噪声特性,为低噪声城市轨道交通车辆的开发提供参考。

After a study of the acoustical property of sheared resilient wheel through mode calculating, which manifested that the noise produced in sheared resilient wheel is much lower than that produced in rigid wheels, the author suggests that the development of resilient wheels be an effective way to decrease the noise and vibration of URT.
