| 摘 要： | 在原始截面离散数据点的基础上,给出了面向工程实际的中弧线几何造型方法和基于离散数据点的内形曲线参数化方法;深入分析了UG(Unigraphic)系统参数化造型的实质;给出了可行的参数化方案;结合面向对象的思想和创成式的建模方式,实现了变壁厚叶身参数化设计.该模块基于UG/OpenAPI接口,采用即时记录数据点和标记回溯点的方式,在交互中可以实时动态修改,达到"所见即所得"的效果,并在实际应用中得到有效验证.

| Abstract: | A new method about parametric design of variational-wall-thickness blade body was provided,which could effectively solve the problem that how to modify the blade cross shape.It is convenient and effective to adjust the blade wall thickness,then to improve the blade performance.An effective method that how to acquire the mean curves was given and proved step by step,which could gain the real mean curves by using the geometric modeling function based on unigraphics(UG).It provides a technology route that real... |
