Coriolis acceleration demonstrator

Abstract

The invention relates to a Coriolis acceleration demonstration instrument. The Coriolis acceleration demonstration instrument comprises a support, a transmission module and a display module. The transmission module is installed on the support and comprises a gear mechanism, a cylindrical fixing sleeve with the top and the bottom open, a hand-operated crank, an inner shaft, a cylindrical outer shaft, a transmission shaft and a vertical shaft, wherein the crank is connected and fixed to one end of the transmission shaft, the front end and the rear end of the transmission shaft are respectively fixed to the support in a threaded connection mode through a fixing bearing, the inner shaft is internally connected into the outer shaft through a bearing, the outer shaft is fixedly connected into the fixing sleeve through a bearing, the upper end of the outer shaft is higher than the edge of the fixing sleeve, the upper end face of the outer shaft is provided with at least four pairs of threaded holes used for being connected with the display module and a data acquisition module, and the fixing sleeve is in the vertical state and fixedly connected to the support. According to the Coriolis acceleration demonstration instrument, visual and interesting phenomenon demonstration can be achieved, data monitoring is convenient, and the modules are convenient to disassemble or assessable; the Coriolis acceleration demonstration instrument is easy to operate and can be taken to a classroom to well assist a teacher in completing the teaching content of Coriolis acceleration demonstration.

Description

technical field [0001] The invention relates to a Coriolis acceleration demonstration device, specifically, it is mainly used in the Coriolis acceleration teaching link in the classroom of theoretical mechanics, to help teachers explain this part of the content, and at the same time help students digest and absorb. It integrates Coriolis acceleration phenomenon display and data acquisition, including three parts: transmission module, phenomenon display module and data acquisition module. The teacher provides power for the whole device by rotating the handle, and connects with different modules through the transmission module to achieve different Features. [0002] technical background [0003] Coriolis acceleration is an acceleration generated by the movement of the moving point on the rotating moving system, and its relationship is Many phenomena in life are caused by Coriolis acceleration, for example, when a train travels north and south, the forces on the left and right...

AI Technical Summary

Problems solved by technology

[0004] There are only a single type of Coriolis acceleration demonstrator on the market. Although it can simulate the existence of Coriolis force, its display form is quite different from the principle of Coriolis acceleration. It is mainly a kind of Coriolis acceleration phenomenon. display, but cannot intuitively explain the principle of Coriolis acceleration, so it still cannot effectively help teachers explain and students learn
