Development of Truck Frame and Bolster For New-York EMU
- 발행 : 2005.05.01
초록
The truck frame of railway vehicle is important structure supporting the various loadings during running on the railway. The verification of sufficient strength on truck frame is essential in case of EMU carrying many people. To verify the safety of truck frame, the actual loading conditions should be considered ast design stage. This paper is describing that the development procedure of truck frame and bolster changed from existing casting frame to new welded frame for New-York EMU, also introducing the design regulations for new welded truck frame. Additionally the dynamic accelerations on the truck were measured to insure the actual loadings on service running condition, and the procedure and results of this test are described in this paper.
