Embodiment Construction
[0016] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with the examples, which are only used to explain the present invention, and do not constitute a limitation to the protection scope of the present invention.
[0017] This embodiment provides a numerical simulation research method for three-roll roll forming, and the steps of the research method are as follows:
[0018] Step 1: According to the technical parameters of the bending machine, determine the geometric dimensions of the model's rollers and strip steel;
[0019] Step 2: According to the stress situation in the forming process, while reducing the calculation time, choose a two-dimensional plane model for modeling;
[0020] Step 3: Select three forming rollers as analytical rigid bodies, and determine the analysis steps and boundary conditions;
[0021] Step 4: Set each surface of the forming roller, steel plate, and pressing plate ...
