城际动车组铝合金车体结构设计与性能

Study of Intercity EMU Carbody Structure

根据城际动车组的运用特点,以CRH3A型城际动车组车体结构为例,在最大程度上满足车体的高强度及轻量化的要求及标准下,从车体材料的选择、车体断面设计、车体结构设计、计算分析验证及试验对比等方面进行研究,提出了城际动车组车体结构的设计思路和方法.

The carbody structure of intercity EMU with CRH3A is exemplified according to intercity EMU running characterisitcs. Under condition and criterion of meeting the high strength and lightweight carbody, the research focuses on the choice of the carbody materials,design of the carbody profile, design of the carbody structure,the validation of design calculation, the contrast test and design principles,and the methods of the intercity EMU carbody structure are proposed.
