Abstract

The invention discloses a motion track research device of points, comprising a transparent thin drawing board (1), a drawing pen clamp (2), a drawing pen (3), a relative rotating rod (4), an adjustable sliding chute (5), an adjustable motor (6), an absolute rotating rod (7), an adjustable sliding chute (8), an 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-(four and five) leaf rose lines can be drawn by adjusting the positions of the adjustable motor (6) on the absolute rotating rod (7) and the relative rotating rod (4) and adjusting the rotating speed ratio of the adjustable motor (9) to the 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.

Description

technical field [0001] The invention relates to a motion trajectory research device for a theoretical mechanics experiment point, and belongs to the technical field of teaching experiment devices for colleges and universities. Background technique [0002] Kinematics studies the geometric properties of motion, including the law of the position of an object in space over time, the trajectory, velocity, and acceleration of an object, without involving the relationship between motion, force, and mass. Since the mass of the object is not involved in kinematics, the object is simplified into two models of point and rigid body according to the nature of the research problem. The so-called point refers to a geometric point regardless of size and quality, and a rigid body is an indeformable object composed of countless points. [0003] When studying the motion of an object, a reference body must be selected. The coordinate system fixed on the reference body is called the reference...
