摘要
简述非均匀有理B样条曲线、曲面在列车头部外型设计中的应用方法,并用一张曲面统一表达了包含解析面和自由曲面在内的复杂列车头部外型,具有整体的C_2连续性,给内包络面的求解和板梁的数控加工以及有限元建模带来极大方便。
In this paper, the application of Non - uniform Rational B - spline curve and surface on configuration design of locomotive has been introduced. Formed with analytic and free surfaces, one uniform surface has been used to describe the locomotive configuration. The surface with C2 continuity has great advantages in obtaining its inner offset surface, in numerical control processing of shell - beam and in finite element modeling.
