온습도 변화에 따른 철도차량 바닥재의 변형
Deformation of the floor structure of railway vehicle depending on temperature and humidity
- 발행 : 2008.06.12
초록
The floor structure of railway vehicle can deflect and warp due to variation of temperature and humidity at the inside and outside of vehicle. In this study, its temperature and humidity characteristics was investigated experimentally for beam and plate specimen and numerically for the floor structure assembly. The temperature and humidity characteristics of a part were measured and the deformation and stress distribution of the floor structure were calculated using a commercial software. And the warp deformation of the plywood was measured experimentally. The results show that the temperature and humidity effects on the floor structure are the important factor to decide the strength and the quality of the floor structure of railway vehicles.
