摘要
根据鼓形面拟合双曲率侧窗玻璃的设计原理,提出了基于双曲率玻璃参数化模型的优化方法.采用知识工程理论以及知识驱动的优化过程,结合模拟退火算法优化,得出最佳的鼓轴位置以及最优的鼓形面,使最优鼓形面的拟合误差控制在0.4mm以内,提高了拟合精度.应用鼓形线原理生成升降器导轨曲线,并模拟出双曲率玻璃在升降导轨中的运动,优化后的运动误差控制在0.4mm以内,提高了玻璃的运动质量.优化分析结果表明,该优化方法可满足双曲率玻璃的设计精度要求.
In order to fit the shape of a dual-curvature glass to a drum surface,an optimization method for the dual-curvature glass parameter model was brought up.Based on the theory of knowledge engineering and the knowledge driving optimization the simulated annealing arithmetic was used to search out the best drum axis position and the optimal drum surface.The fitting precision is thus increased and the error of the optimal drum surface was below0.4 mm.The theory of drum line was applied to produce the guide curve and the movement of the dual-curvature glass in the regulator was imitated.The error of the movement after optimization is below0.4 mm and the quality of glass movement is improved.The analysis results show that the optimizing method can meet the needs of the design precision of dual-curvature glasses.
