摘要:
针对汽车行李架铝型材拉弯成型问题，运用ABAQUS 有限元分析软件，建立型材拉弯成形过程的有限元模型，通过对A6043 铝型材结构件进行拉弯成形正交数值试验，研究预拉量、包覆拉伸量、补拉量和摩擦系数等拉弯成形关键工艺参数对型材回弹量的影响规律，结果表明:在一定拉伸范围内，回弹量随预拉量、包覆拉伸量、补拉量的增大而减少，随摩擦系数的增大先减小后增大?工艺参数中包覆拉伸量对回弹结果的影响最大，达到3%，回弹量趋于稳定?当预拉量为1%、包覆拉伸量为3%、补拉量为1%、摩擦系数为0.1 的工艺参数下，不规则铝型材汽车行李架拉弯成形后的回弹量最小。
Abstract:
Aiming at the problem of stretch-bending forming of automotive luggage rack aluminum profiles, ABAQUS finite element analysis software was used to establish a finite element model of the stretch-bending process. Through the orthogonal numerical experiment of stretch-bending forming of A6043 aluminum profile structural parts, the influence of key process parameters of stretch-bending forming such as pre-stretching amount, coating stretch amount, supplementary stretch amount and friction coefficient on the springback of the profile was studied. Results show that within a certain stretching range, the amount of springback decreases with the increase of the pre-stretch, the amount of coating stretch, and the amount of supplementary stretch, and it first decreases and then increases with the increase of the friction coefficient. In the process parameters, cladding stretch amount has the greatest influence on the springback results. When the maximum coating stretch reaches 3%, the springback tends to be stable; when the pre-stretch amount is 1%, the coating stretch is 3%, the supplementary stretch is 1%, and the friction coefficient is 0.1, the elasticity of the irregular aluminum car roof rack after bending is the smallest.
