Abstract

The invention provides a coriolis acceleration demonstration instrument and relates to an acceleration demonstration instrument. The coriolis acceleration demonstration instrument is provided with a drive unit and a demonstration unit, wherein the drive unit is provided with a lower electromotor, a transmission shaft bevel gear, a lower electromotor bevel gear, a transmission shaft spur gear, a center shaft spur gear, a transmission shaft, a center shaft, a cross-shaped gear, a turntable cover, a turntable and a base; the demonstration unit is provided with an upper electromotor, a turntable cover, a turntable, a standard gear, a standard rack, a piston, a bolt, a ball feeding device, a catapulting device, a switch base and a touch wall. The coriolis acceleration demonstration instrument has the benefits that under the situation that each system normally runs, a small ball is popped up from the catapulting device and hits different positions of the touch wall according to different rotating speeds, and a lamp on the corresponding touch wall is lightened, so that the effect of an object under the action of coriolis force is embodied, that is, the effect of the coriolis acceleration on physical motion is demonstrated; not only is the weight of an experimental instrument reduced, and is the limitation on the using range reduced, but also the continuous effect of the coriolis acceleration on a mobile object as well as a motion track can be more intuitively observed.

Description

technical field [0001] The invention relates to an acceleration demonstration instrument, in particular to a Coriolis acceleration demonstration instrument when an object is subjected to Coriolis force in a rotating non-inertial system. Background technique [0002] It can be known from theoretical mechanics that the movement of an object in a rotating non-inertial system will be affected by the Coriolis force, and its movement will be affected by the Coriolis acceleration. The existing "Coriolis acceleration" demonstrator is usually divided into two types according to the type of moving object, the belt type and the fluid type, which are relatively complicated and difficult to observe. [0003] Chinese patent CN102129802A discloses a three-dimensional mechanical belt-type Coriolis acceleration tester, which includes a moving part, a relative moving part, a frame and an electrical part; it is composed of various parts such as a cylindrical pulley, a pulley shaft, and a doubl...
