Water Droplet Motion
Operation: 1. Turn the handwheel; 2. Observe the "mechanical ripples" formed by the rings. Function Overview: The exhibit consists of a cam mechanism set, discs of different colors, etc. Turn the handwheel to drive the cam mechanism to rotate, and you will see the colored rings ripple outward one after another, like ripples spreading on the water's surface. Scientific Principle: How are the beautiful "mechanical ripples" formed? Look at the colored rings rippling outward one after another—don't they look like ripples after a drop of water falls into a calm water surface? The rings rising and falling one after another actually all rely on the set of blue cams below. When you turn the handwheel, the cam set begins to rotate, pushing up the metal rods above each cam, and the metal rods in turn push the rings to move up and down. The installation angles of this set of cams are designed in advance, so the colored rings will show a regular up-and-down motion, just like ripples spreading on the water's surface. When you turn the handwheel, the handwheel performs circular motion, but by the time it reaches the metal rods, the motion becomes linear reciprocating motion. This is the function of the cam mechanism, which is often used to convert circular motion into continuous linear reciprocating motion. Therefore, it is widely used in various mechanical control devices. For example, in a household sewing machine, there are several cam mechanisms that serve different functions.
