基于空间曲线的异型截面构件的三维造型设计

Tri-dimension Design of the Member with Special Sections Based on Space Curves

本文应用刚体运动学的达朗伯─—欧拉原理，将构件不同位置的法截面视作绕一系列转动轴依次转动的结果。据此，推出具有空间曲线的异型截面构件的三维造型数学公式，可供产品设计及绘图软件二次开发使用。

The normal sections at the different places of a member could be taken as the results of their rotating about a series of axes upon the Dalembert-Euler's principle on the rigid body kinematics. And then the math formulae for three dimensional moulding of a special section member with space curves have been derived which could be used for product design and development of drawing software.
