| 摘 要： | 在CAD软件中基于NURBS理论对发动机缸盖气道外壁进行构建,截取原气道截面线并偏移截面线,抓取偏移截面线节点建立B样条曲线,选取四条边界B样条曲线并定义内部控制曲线生成外壁曲面,合并外壁曲面实体化生成外壁实体。

| Abstract: | The intake port wall of a certain cylinder head is constructed based on NURBS theory with CAD software. The method is to intercept and shift the original port cross section lines,snatch the pitch-points of the shifted cross section lines to build B-spline curves,choose 4-boundary B-spline curves and define internal control curves to create curved ektexines,and then consolidate the curved ektexines to build ektexine body. |
