摘　　要：对成形后侧壁模型进行应力应变分析,用挠度理论得出了卷曲的机理及控制方法,并以典型汽车门槛内加强板为例,借助有限元分析软件论证了该控制方法是行之有效的。Analysis was made on the stress and strain of a model with side-wall curl after its formarion; and the mechanism for the side-wall curl and the control method were achieved via the deflection theory. Taking a typical inner reinforcing plate of automobile doorsill as an example, the control method has proved feasible according to the finite element analysis software.
