本文用比拟法推得了刚体一般运动的螺旋轴方程。这个方法就是将刚体一般运动与空间一般力系进行类比,而一般力系的中心轴方程是巳知的。这是推导螺旋轴方程的一种新的简便的方法。
In this paper, the rigid axis generalized motion of the screw axis equation was deduced by analogy. This method is analogous to the general rigid body motion and to the general space force system, whereas the central axis equation for a general force system is known. This is a new and easy way to derive the helical-axis equation.
