基于Pro/Engineer的变截面冷弯成型机三维动态仿真

Three dimension dynamic simulation of flexible roll forming machine with Pro/Engineer

变截面冷弯成型产品作为重要构件在建筑、汽车制造、传播制造、电子工业等许多领域得到了广泛的应用,这些领域对变截面的产品有很大需求,变截面冷弯成型机组可以生产变截面冷弯型钢产品。采用计算机技术的变截面冷弯成型成为辊式冷弯成型技术的发展方向。虚拟样机技术可以在实际制造物理样机之前对产品进行设计修改,提高产品性能,加速新技术向新产品的转化。利用Pro/Engineer建立变截面冷弯成型机的虚拟样机模型,并对变截面冷弯成型机的运动情况进行仿真分析,为设计人员提供进一步的理论设计依据,为物理样机的研制提供技术支持。

Variable cross-sections has spread fabrication as important component in the building, the automobile making, many field such as electronic industry etc. has got broad application, these fields have had very big need to unexpected turn of events cross section product. The flexible roll forming machine sets can produce profiles with variable cross-sections. The flexible roll forming technology which combines with the computer technology becomes a developing direction of the new roll forming technology. Virtual prototyping can not merely revise and design conveniently through virtual prototype before making physics prototype actually, improve the properties of product, accelerate the transformation from new technology to new products. This paper sets up the virtual prototyping model of forming machine with Pro/Engineer. Through the analysis for the movement situation of flexible roll forming machine, it provides a further basis of designing for the designer and it offers the technical support for the research and produce of physics model machines.
