Experimentation on Vibration Transmission Characteristics of Modern Tram Tracks

  • 摘要: 为探讨现代有轨电车不同轨道的振动传递特性,以某市现代有轨电车为例,对3种不同的轨道(未采取减振处理的普通轨道、安装弹性包覆材料的普通轨道和嵌入式轨道)进行测试. 基于锤击试验原理,获取了钢轨振动衰减率、轨道各部件的频响特性和插入损失,并与其它减振轨道进行了比较. 结果表明:嵌入式轨道的钢轨振动衰减率表现出明显的频率相关性,其在1 600 Hz频带可达5.9 dB/m;嵌入式轨道的第1个钢轨共振点出现在频率160 Hz附近,其频响函数幅值和共振频率均比未采取减振处理的普通轨道小;总体上,与安装弹性包覆材料的普通轨道和其它减振轨道相比,嵌入式轨道在中高频表现出更好的钢轨纵向减振效果,故理论上能够对轮轨噪声起到良好的抑制作用.
