随着科学技术的迅速发展,三维技术已应用于多个领域,实践证明,在水利水电行业中运用三维设计是切实可行的。本文主要以双层取水口作为例子,运用CATIA的各种功能设计三维模型,并以此为基础设计完成ANSYS模型的导入,再现三维设计空间结构的形状,有效证明了三维设计的科学性与发展方向。 With the rapid development of science and technology, three-dimensional technology has been applied in many fields. Practice has proved that it is practicable to apply 3D design in water conservancy and hydropower industry. In this paper, a double-layer water intake is taken as an example to design a three-dimensional model by using CATIA’s various functions. Based on this, the import of ANSYS model is completed and the shape of three-dimensional design space structure is reproduced. This proves the scientific and development of 3D design direction.
