On Study the Safety Diagnosis Assessment of EMU's Carbody
- 발행 : 2004.06.01
초록
This paper describes the structural analysis result of accident EMU(Electric Multiple Units). Structural analysis of EMU was performed for the criteria of safety assessment. Structural analysis using commercial I-DEAS software provided important information on the stress distribution and load transfer mechanisms as well as the amount of damages during rolling stock crash. Tensile tests were performed on two different types of specimens in order to evaluate the strength changes before and after damages, obtained from plastic deformed area and nondeformed region of the accident EMU. The structural analysis and tensile test results have been used to provide the critical information for the criteria of safety assessment.
