铝合金骨架制作工艺及应用浅析

Analysis of manufacturing process and application of aluminum alloy skeleton

近年来新能源客车得到蓬勃发展。在着力提升电机、电池、电控等核心部件性能的同时,减轻车身重量也是提升整车续航能力的重要措施。铝合金相对价格低廉,防腐性能好,成为骨架制作的首选材料。但铝材导热性强、热容量大等特点导致骨架制作工艺与传统材料有很大的区别,需制定完备的方案。

With the vigorous development of new energy buses and the intensification of market competition, the competition of products has been penetrated into the parts.While enhancing the motor, battery, electronic control and other core components, reducing the weight of the bus body is the important measure to en- hance the vehicle endurance. As the aluminum alloy is relatively inexpensive and has good anti-corrosion performance, it naturally becomes the first selection of the material for production of skeleton. But because of high thermal conductivity and large heat capacity of aluminum, which causes the production process of skeleton different from the traditional material, it is necessary to make a complete proposal.
