Description
技术领域 technical field
本实用新型涉及一种力学演示实验仪器，具体为一种往复运动演示仪。 The utility model relates to a mechanical demonstration experiment instrument, in particular to a reciprocating motion demonstration instrument.
背景技术 Background technique
往复运动是物理学中常见的一种运动形式，目前已有一些往复运动的演示装置，如单摆的摆动、小球在一凹型曲面上的来回滚动等，这些装置形式较为单一，缺乏趣味性和变化。 Reciprocating motion is a common form of motion in physics. At present, there are some demonstration devices of reciprocating motion, such as the swing of a simple pendulum, and the rolling of a small ball on a concave surface. These devices are relatively simple in form and lack of interest. and change.
发明内容 Contents of the invention
本实用新型的目的，是开发一种基于机械能守恒定律的具有较强趣味性的往复运动演示仪。 The purpose of this utility model is to develop a reciprocating motion demonstrator with strong interest based on the law of conservation of mechanical energy.
为了解决上述技术问题，本实用新型采用以下技术方案： 一种往复运动演示仪，其特征是：包括底座、“><”形导轨，以及作为滚动物的双圆台体，其中：“><”形导轨由两个形状、大小相同的“八”字形导轨头部对头部平滑联结构成，“><”形导轨的导轨中部和导轨端口的下方分别通过直杆与底座固定连结，导轨中部的高度大于导轨端口的高度；双圆台体由两个形状和大小相同的圆台上底面与上底面对应连结构成。 In order to solve the above technical problems, the utility model adopts the following technical solutions: A reciprocating motion demonstration instrument, characterized in that it includes a base, a "><"-shaped guide rail, and a double-round platform as a rolling object, wherein: "><" The guide rail is composed of two "eight" guide rails with the same shape and size, which are connected smoothly from head to head. The middle part of the guide rail and the bottom of the guide rail port of the "><" guide rail are fixedly connected to the base through straight rods respectively. The middle part of the guide rail The height is greater than the height of the port of the guide rail; the double circular platform body is composed of two circular platform upper bottoms with the same shape and size and correspondingly connected with the upper bottom surfaces.
本实用新型由于采用上述设计，实验时将双圆台体置于“><”形导轨的任一导轨端口上方，双圆台体会自动沿“><”形导轨在两导轨端口之间来回往复滚动。其原理是：双圆台体从“><”形导轨的导轨端口向导轨中部上滚过程中，其质心的高度逐渐下降，重力做功转换为双圆台体的动能；双圆台体越过导轨中部后在惯性作用下的下滚过程中，其动能转换为重力势能。本实用新型结构简单，构造新颖，趣味性强，有利于加深物理学相关原理的理解。 Because the utility model adopts the above-mentioned design, the double-circle table body is placed above any guide rail port of the "><"-shaped guide rail during the experiment, and the double-circle table body automatically rolls back and forth between the two guide rail ports along the "><"-shaped guide rail. The principle is: when the double-circular table body rolls up from the guide rail port of the "><"-shaped guide rail to the middle of the rail, the height of its center of mass gradually decreases, and the gravity work is converted into the kinetic energy of the double-circular table body; after the double-circular table body crosses the middle of the guide rail, it In the process of rolling down under the action of inertia, its kinetic energy is converted into gravitational potential energy. The utility model has the advantages of simple structure, novel structure and strong interest, and is conducive to deepening the understanding of relevant principles of physics.
