燃气轮机叶片实体建模

3D solid modeling of the leaf of gas turbine

提出燃气轮机空心叶片实体建模的新方法,即采用UG软件对燃气轮机叶片进行精确实体造型,利用UG自由曲面及片体的形成、修剪、精确缝合,建立空心叶片,充分发挥transform的精确定位,结合布尔运算形成精确的叶片复杂的内部结构,为结构强度、温度场等有限元分析提供基础。

A new method of making 3D solid m deling of the leaf entity of the gas turbine is introduced, which uses UG software to construct precise entity for the leaf, forming, trimming and sewing the sheet of leaf to establish the geometric model exactly. The precise orientating function of transform menu, combined with Boolean operation is exerted to forms the complicated internal structure of leaf. The geometric model lays good foundation for finite dement analysis of structural strength, temperature field and so on.
