| 摘 要： | 对于复杂型面的曲面钣金零件,对其进行曲面质量分析是曲面模型创建完毕后必不可少的工作内容.目前曲面质量分析常用的多截面曲率梳、等照度线和反射线方法已经比较成熟,但采用高斯曲率的曲面质量分析方法还有很多工作要做.针对曲面高斯曲率的含义与表现特征,重点探讨了曲面分别在G0、G1和G2连续情况下的高斯曲率色标分布特点.研究表明,应用高斯曲率方法可以快速完成曲面质量的评价,也可为后续的零件模具加工制造提供可靠的理论依据.

| Abstract: | For complex surface sheet parts,to analysis its surface quality is a essential work after the model created.The surface quality evaluating methods,such as multi-section curvature comb,isophotes mapping and reflection lines have been perfect,but the method of Gaussian curvature is no more maturity.In view of the meaning and expressional characteristics of surface Gaussian curvature,the distributional features of color patch for Gaussian curvature in case of G0,G1 and G2 continuity state have been discussed.The result verified that the method of Gaussian curvature can be applied to complete the evaluation of surface quality,and it will also provide reliable theoretical evidence for the subsequent mould manufacturing of surface parts. |
