为解决冷轧带钢板形和轧机动作的模型驱动与人机交互问题,以冷轧带钢出口张应力横向分布和板带屈曲判别模型为基础,提出了基于VRML高程格网(Elevation Grid)节点的虚拟带钢建模技术,实现了边浪、中浪等常见板形缺陷的量化解析预测和三维动态可视化呈现,并结合国内某厂2 230 mm冷连轧机组出口板形仪实测数据,将浪形几何参数数值预测结果与现场带钢板形缺陷进行对比,两者吻合良好。在此基础上,以650 mm UCM单机架可逆冷轧机组为对象,利用MATLAB/Simulink 3D Animation工具箱,将轧机、带钢、厂房车间等VRML三维场景与轧制过程Simulink仿真模型进行了通讯集成,为虚拟现实系统开发奠定了基础。
In order to solve the problem of model-driven and human-computer interaction of cold-rolled strip shape and mill motion, based on the lateral tensile stress distribution and buckling discriminant model of cold-rolled strip, a VRML-based Elevation Grid node The virtual strip steel modeling technology is used to realize the quantitative analysis and the 3D dynamic visualization of the common plate defects such as the side waves and the medium wave. Based on the measured data of the deformable profile of the 2 230 mm tandem cold rolling mill in a certain country, The results of numerical prediction of wave geometry parameters are in good agreement with those of strip shape defects on site. Based on this, the 650 mm UCM reversing cold rolling mill with single stand was used as object, the VRML 3D scene of rolling mill, strip and workshop was simulated with Simulink simulation model of rolling process by MATLAB / Simulink 3D Animation toolbox , Which laid the foundation for the development of virtual reality system.
