Research on the Generation of Three-dimensional Model of Complex Curved Surface for Racing Artificial Track:Complex Curved Surface Generation of National Sliding Centre Track

雪车雪橇赛道表面为非欧、非线性复杂曲面,赛道数字三维模型是保障赛道设计与施工精度的基础。本文以国家雪车雪橇中心赛道设计实践为基础,针对赛道数字三维模型生成技术进行研究归纳,通过借助参数化软件(Grasshopper)将赛道设计方提供的数据参数,基于参变量的属性定义和几何关系定义转化为包含数字信息的三维模型,并引入结构参数生成完整赛道三维模型。

Bobsleigh track surface is a non-Euclidean,nonlinear complex curved surface,making its digital three-dimensional model the basis of ensuring the accuracy of track design and construction.Based on the design practice of the track of National Sliding Centre,this paper guides the model generation procedure.This process essentially involves converting data parameters provided by the track designer into digital information with the help of parametric software(i.e.,Grasshopper)based on their geometrical relationship,and making a complete digital three-dimensional track model by attaching the structural parameter.
