Abstract

Railway transportation is important for public transportation in Thailand like Bangkok Mass Transit System (BTS) and Mass Rapid Transit (MRT). Therefore, the organization of national development has objective to develop in railway transportation. Moreover, they are planning to build railway in Thailand to connect between ASEAN and China. There are many researchers who studied about the railway transportation infrastructure by using various methods. However, in this studies, waves of high-speed train were investigated by using different velocities into force and free vibration equations from structural dynamic. Then the results showed that shorter range was happened due to the vibration waves of high-speed trains than waves of low-speed ones. Finally, finite element software was used to get characteristics of the waves. The results proved that the vibrations waves were strong at first 1-5meter, however, at the distances of 5-15meter waves were decreased significantly in intensity. It was reduced to the end or there was no effect at the distance more than 18meter waves from the wave source.

研究高速列车模型振动波的特性

铁路运输是泰国公共交通的重要组成部分，如曼谷公共交通系统(BTS)和快速轨道交通(MRT)。因此，国家发展组织对铁路运输的发展具有客观的要求。此外，他们还计划在泰国修建连接东盟和中国的铁路。许多研究者运用各种方法对铁路交通基础设施进行了研究。然而，在本研究中，采用不同速度的力和结构动力学的自由振动方程来研究高速列车的波动。结果表明，高速列车的振动波比低速列车的振动波作用范围更短。最后，利用有限元软件得到波浪的特性。结果表明，振动波在1 ~ 5m处较强，但在5 ~ 15m处振动波强度明显减弱。在距离波源超过18米的距离上，它被缩小到末端或没有影响。
