摘要
Abstract
Key dimensions of car body composition of Intercity EMU have speed of 200 kilometers per hour involve length,height,deflection and entrance height.After welding length reduced,height of the car body and entrance height decrease,the two ends bend upwards.Process allowance can control length Effectively.Widen the side wall before welding can control height Effectively.Prefabricated deflection on side wall and Fixture can control deflection of the car boday Effectively.关键词
