摘　　要：为了快速、高效、准确地获得车窗侧玻璃曲面设计的最优解,以保证整车造型姿态的协调性。结合二次开发和多目标优化算法的计算优势,简化了传统设计方法的流程,使整个拟合过程自动计算,通过算法驱动程序拟合车窗玻璃的CAS曲面,得到和CAS面误差很小的三维曲面数据。该方法能够快速高效的拟合CAS曲面,减少设计周期延迟并提高设计质量,使设计更加数字化,设计衰减最小化,使得造型设计的自由度更大。In order to obtain the optimal solution of window side glass surface design quickly,efficiently and accurately,the coordination of vehicle modeling posture is ensured.Combined with the advantages of secondary development and multi-objective optimization algorithm,the flow of traditional design method is simplified,the whole fitting process is calculated automatically,and the CAS surface of window glass is fitted by the algorithm driver.Threedimensional surface data with small error with CAS surface are obtained.This method can quickly and efficiently fit CAS surface,reduce design cycle delay and improve design quality,make design more digital,minimize design attenuation and make modeling design more freedom.
