Vibration Transmission of Railway Floor Structure due to Connecting Materials

연결재료에 따른 철도차량 바닥구조의 진동전달

  • Published : 2009.11.01


The sources of the vibration of railway vehicles in the cabin are usually bogie, axle, and wheel. The vibrations are transmitted through the floor structures of railway vehicle. The floor structure is the combination of bottom plate, plywood, and rubber. In this research the vibration transmission is measured experimentally and analyzed numerically to find the transmission characteristics of the vehicle floor structures. The result shows that the vibration characteristic of soft rubber is better than hard rubber or wood as the connecting material between the bottom plate and the plywood.
