中文摘要：

B样条方法是常用工程造型软件的理论基础,是工科类学生基础理论课程的重点内容。但是由于在教学中理论和实践脱节,多数学生的现状是能够熟练应用如CAD等工程造型软件,但并不明白其原理。为实现理论和实践的无缝连接,遵循国家出台的＂卓越工程师教育培养计划＂,在车身逆向实验教学环节中,增加B样条方法的仿真分析内容。首先,学生应用ATOS光学三维坐标扫描仪,对车身翼子板进行扫描,获得点云数据;然后,根据B样条理论,编写程序,实现翼子板曲面或轮廓曲线的重构;最后,将自己重构的曲面或曲线与ATOS的结果进行比较。这种集课堂教学、实验教学和仿真分析于一体的教学模式,是＂卓越工程师教育培养计划＂的有益尝试。

英文摘要：

B spline theory is the basis of the engineering modeling software,and is also the key content of the required course in colleges of engineering. However,because of the disconnection between theory teaching and experiment courses,the fact is that the majority of students are able to use the engineering modeling software such as AUTO-CAD,but they do not understand the principle. Aiming at the problem,under the guidance of the ＂ excellent engineer education and training plan＂,the simulation analysis of B spline interpolation is introduced to the experiment in the course of ＂vehicle body structure design＂. Firstly,students use the ATOS optical 3D scanner to scan a fender on a car,on which surface the coordinates of a set of points are obtained. Secondly,students are demanded to develop program files to reconstruct the contour curve or the surface of the fender by themselves. Finally,the results are compared with the ones of ATOS. The teaching pattern combining theory teaching and experiment as well as simulation analysis is a helpful try.
