浅析铝合金零件定位方案

Analysis of Aluminum Alloy Parts Location Scheme

铝合金材料在汽车白车身中的运用是汽车轻量化发展的必然趋势,与传统钢结构车身相比,它的耐腐蚀性、机械强度和刚度方面性能更加优异,在现有某车型项目下车体大量运用,如门槛、座椅横梁、中通道等。对铝合金零件精度质量影响因素与铝合金零件定位策略的制定进行了讨论和分析,解决了铝合金件制车身尺寸精度水平不高的问题。

The application of aluminum alloy in car white body is an inevitable trend of the auto lightweight development.Compared with traditional steel white body,it has better performance in corrosion resistance,mechanical strength and stiffness.It is widely used in the existing car white body project,such as threshold,seat crossbeam,longitudinal beam,etc.In this paper,the factors affecting the accuracy and quality of aluminum alloy parts and the formulation of positioning strategy for aluminum alloy parts are analyzed.And the problem of low dimensional accuracy of aluminum alloy body is solved.
