摘要
以一款待开发和生产的汽车悬架6082铝合金控制臂为研究对象,根据控制臂的外形轮廓,采取辊锻-弯曲-模锻的工艺方案进行生产。通过试验获得了6082铝合金的本构方程中的参数,确定了工艺方案和相关参数,设计了辊锻、弯曲压扁和模锻的模具。根据Deform-3D有限元分析计算方法,对控制臂成形过程进行了模拟。为验证工艺方案的合理性,对该款控制臂进行锻造,在锻件上切取试棒,并在材料拉伸试验机上进行力学性能试验。在上述研究的基础上,分析了不同摩擦系数对模具寿命和锻件损伤的影响及不同应变速率对锻件等效应力的影响。
For 6082aluminum alloy control arm of automobile suspension to be developed and produced,based on its outline,the technological scheme of roll forging-bending-die forging was adopted,and the parameters of constitutive equation for 6082 aluminum alloy were obtained by experiments.Then,the process scheme and related parameters were determined,and the molds of roll forging,bending and die forging were designed.According to the finite element analysis and calculation method of Deform -3D,the forming process of control arm was simulated.In order to verify the rationality of forging process scheme,the 6082 aluminum alloy control arm was forged,and the mechanical tension test was conducted by cutting sample from the forged ann.On the basis of the above research,the influences of different friction factors on mold life and forging damage and the influences of different strain rates on equivalent stress of forging were analyzed respectively.
