The present work was intended to apply a newly developed high damping ferrous material, Fe-5%Ni-15%Mn alloy, to transportation facilities as a construction material. It was expected that the alloy would be fit for the blocking of noises generating from them, because it had fairly enough mechanical properties with good damping characteristics. Moreover, the alloy has been showed an excellent resistance to the corrugation wear.Two forged blooms with 11m length were made from a 7-ton ingot, then they were longitudinally machined and shaped into 60kg-Shinkansen rails.A noise test including a weight falling test, a running motor car test and an impulse hammer test was carried out on the trial rails. In the weight falling test, the maximum impact load and the accelerated force attained to 30tons and 100kN, respectively. The running motor car test was carried out with a diesel car moveing inertly at about 20km/hr. In order to shut off any noises from the engine mounted on the car, it was cut off immediatly before the testing rails connected to the runway. To detect damping behavior of the rail, 10 of vibration sensors were attached on it. Furthermore, a noisemeter was set up closely by the rail. the impuls hammer test was done not only under the anchored but also the free beam conditions.Good results have been obtained in these tests. The level of noise was decreased as much as 5dB in the traial rail compared to those of a standard 60kg rail.

本工作旨在将新开发的高阻尼铁材料--Fe-5%Ni-15%Mn合金作为建筑材料应用于交通设施。由于该合金具有较好的力学性能和良好的减振特性，因此有望适合于阻隔由其产生的噪声。此外，该合金还表现出了良好的抗波纹磨损性能。用7吨重的钢锭锻造了两个11m长的大方坯，然后将它们纵向加工成60 kg重的新干线钢轨。在试验钢轨上进行了噪声测试，包括重量下降试验、摩托车行驶试验和脉冲锤击试验。在落重试验中，最大冲击载荷和加速力分别达到30吨和100kN。机车行驶试验是在一辆柴油车以大约20公里/小时的速度惯性移动的情况下进行的。为了切断安装在汽车上的发动机的任何噪音，在测试钢轨连接到跑道之前立即切断了发动机的噪音。为了检测钢轨的减振性能，在钢轨上安装了10个振动传感器。此外，噪声测量仪紧挨着铁轨安装。冲击锤击试验不仅在锚固条件下进行，而且在自由梁条件下也进行，取得了良好的试验结果。与60公斤重的标准钢轨相比，传统钢轨的噪声水平降低了5dB。
