1铝合金车身结构简介铝合金材料刚开始主要用于高档车辆的外板件,随着铝合金材料相关技术的不断完善,现用于内板件,甚至出现了全铝车身,如奥迪A8车的全铝车身。有部分车型采用前铝后钢的车身结构,如宝马5系车采用了钢制车身和铝制车首(主要在发动机室)的车身结构,主要原因是基于平衡车身前后配重以提升操控性。而宝马X5车仅在车身前半部用上了少数铝合金零件,其整体结构仍为钢制。2车身铝合金内板件的连接方式分析
1 aluminum alloy body structure profile Aluminum alloy material is mainly used for the outer plate of high-end vehicles, aluminum alloy materials with the continuous improvement of technology, is now used in the plate, and even the emergence of all-aluminum body, such as the Audi A8 car Full aluminum body. Some models use the bodywork of the aluminum front steel body. For example, the BMW 5 Series uses a steel body and an aluminum head (mainly in the engine compartment). The main reason for this is that the front and rear counterweights are balanced to improve handling . The BMW X5 car only in the first half of the body with a few aluminum parts, the overall structure is still steel. 2 body aluminum alloy plate connection analysis
