点的运动轨迹研究装置
摘要：
一种点的运动轨迹研究装置，该装置包括，透明薄绘图板(1)；绘图笔夹具(2)；绘图笔(3)；相对旋转杆(4)；第二调节滑槽(5)；第二可调电机(6)；绝对旋转杆(7)；第一调节滑槽(8)；第一可调电机(9)；固定支架(10)；滑块(11)；导杆(12)；直线位移传感器(13)。通过调节第二可调电机(6)在绝对旋转杆(7)和相对旋转杆(4)上的位置，调节第一可调电机(9)与第二可调电机(6)的转动速度之比，可以绘出直线、抛物线、圆、椭圆、叶形线、双绞线、摆线、阿基米德螺线、心脏线、三叶玫瑰线的运动轨迹。本发明可用于运动学教学中点的运动轨迹的演示和实验。
摘要（英）：

The invention discloses a motion track research device of points, which comprises a transparent thin drawing board (1), a drawing pen clamp (2), a drawing pen (3), a relative rotating rod (4), a second adjustable sliding chute (5), a second adjustable motor (6), an absolute rotating rod (7), a first adjustable sliding chute (8), a first adjustable motor (9), a fixed bracket (10), a sliding block (11), a guide rod (12) and a linear displacement sensor (13). The motion tracks of straight lines, parabolas, circles, ellipses, folium, twisted-pair lines, cycloids, Achimedean spirals, cardioids and three-leaf rose lines can be drawn by adjusting the positions of the second adjustable motor (6) on the absolute rotating rod (7) and the relative rotating rod (4) and adjusting the rotating speed ratio of the first adjustable motor (9) to the second adjustable motor (6). The invention can be used for the demonstration and the experiment of the motion tracks of the points in the kinematic teaching.
