Rapid repositioning method for wheel geometric model

The invention discloses a rapid repositioning method for a wheel geometric model, relates to the technical field of wheel design, and sequentially completes wheel feature surface recognition, wheel geometric preprocessing and wheel geometric transformation to obtain the wheel geometric model with standardized and normalized coordinate systems. The position of a wheel geometric model in an existing coordinate system is determined by identifying and preprocessing geometric features of a wheel mounting surface, a center hole and a valve hole. Rapid repositioning of the wheel geometric model can be realized through rotation and translation of the wheel geometric model, so that the positioning speed of the wheel geometric model is greatly improved, full-automatic and rapid repositioning can be realized, and the working efficiency of simulation engineers is greatly improved. 本发明公开了一种车轮几何模型的快速重定位方法，涉及车轮设计技术领域，依次完成车轮特征面识别、车轮几何预处理、车轮几何变换，得到具有标准化和规范化坐标系的车轮几何模型。通过对车轮安装面、中心孔和气门孔的几何特征的识别和预处理，确定车轮几何模型在现有坐标系下的位置。通过车轮几何模型的旋转
