고무차륜형 경량전철개발을 위한 구조체의 강도해석

Carbody strength analysis for a LRT of rubber tire type

The characteristic of “Korea LRT Carbody” is designed by using AED(All Extrusion Design) method. This is developed in Europe and be introduced in this paper minutely. The window type of “Korea LTR” has no supported frame, so the passengers ensure the outside view widely. The passenger's door will designed by plug type - This is the first time in Korea. In this report we have an object to the strength analysis for the carbody design. For the purpose of safety and lightening, we are going to research the section of thickness through optimization design.
