摘要
设计了一种能够绘制双曲线、抛物线的曲线绘制仪。主要应用于教学过程中的黑板绘图,以及圆锥曲线教学时的原理分析。绘制仪原理是根据这两种曲线上每一点都满足的几何关系,再用连杆机构进行模拟,从而达到曲线绘制的效果。
We designs a drawing instrument which can draw hyperbolic and parabolic. It mainly used in the process of teaching drawing based on blackboard and the principle of conic teaching analysis. Based on the geometric relationship that each point on the two curves can meet, the drawing instrument can simulate the curves with link mechanism so as to achieve the effect of drawing the curve.
