The invention discloses a lightweight automobile aluminum alloy hollow control arm production process and belongs to the technical field of automobile parts. The lightweight automobile aluminum alloy hollow control arm production process comprises the following steps that S1, a finite element analysis model is established to perform spectrum expansion analysis; S2, hollow area design is performed on a control arm; S3, a hollow design scheme of the control arm is confirmed; S4, the finite element analysis model is loaded for stress condition analysis; S5, the control arm is subjected to multi-component type split manufacturing; S6, a control arm body and a control arm cover plate are produced and manufactured; S7, the control arm body and the control arm cover plate are clamped; and S8, two heterogeneous materials are subjected to joint welding operations. According to the lightweight automobile aluminum alloy hollow control arm production process, friction stir welding is performed by using multi-component type structure assembling, a cavity area is created, the bottleneck of lightweight of an existing control arm can be solved, and meanwhile, the feasibility of the continuous production manufacturing process is also greatly improved.

    本发明公开了一种轻量化汽车铝合金中空控制臂生产工艺,属于汽车零部件技术领域,包括以下步骤:S1、建立有限元素分析模型进行拓谱分析;S2、对控制臂进行中空区域设计;S3、确定控制臂的中空设计方案;S4、加载有限元素分析模型进行应力状况分析;S5、将控制臂进行多部件式拆分制造;S6、对控制臂本体以及控制臂盖板进行生产制造;S7、将控制臂本体和控制臂盖板进行装夹;S8、将两异质材料进行接合焊接操作。该轻量化汽车铝合金中空控制臂生产工艺,通过利用多部件式结构组装进行摩擦搅拌焊接,创造空腔区域,不仅能解决目前控制臂轻量化的瓶颈,同时对于连续生产制程的可行性也大幅提升。
