Abstract

The invention provides a Coriolis acceleration demonstrating and computing device based on a physical simulation form, and a method thereof, wherein the Coriolis acceleration demonstrating and computing device and the method belong to the field of a kinematics experiment teaching and demonstrating experiment device. The Coriolis acceleration demonstrating and computing device comprises a relative motion device, a convected motion device, a detecting device and an electrical device. The Coriolis acceleration demonstrating and computing device is a novel experiment device and aims to simulate the Coriolis acceleration when the convected motion is rotation and is coupled with the relative motion. Through separately measuring the convected motion and the relative movement, a measurement precision is improved. The measuring result of the Coriolis acceleration demonstrating and computing device is displayed through display screens in a multi-screen display manner, thereby facilitating recording and observation for experiment data change. An experiment device selects ground as a fixed system, selects a rail as a moving system and a rail car as a moving point. A turntable drives the rail to perform convected motion relative to the ground, and the angular speed of rotation is omega. The rail part performs relative motion relative to the rail and the relative speed is Vr. Through coupling between rail rotation relative to the ground and relative motion of the rail car, the Coriolis acceleration ak is generated. The number of the Coriolis acceleration ak is calculated according to a formula ak=2omega*Vr.

Description

technical field [0001] The invention belongs to the field of kinematics experiment teaching demonstration experiment devices, in particular to a demonstration and calculation device and method of Coriolis acceleration based on physical simulation form. Background technique [0002] Coriolis acceleration is the acceleration caused by the mutual coupling between the rotation of the moving reference system and the motion of the moving point relative to the moving reference system. It occupies a large proportion in the teaching of theoretical mechanics and kinematics. At present, the existing Coriolis acceleration experiment instruments have a single function, and cannot have the function of teaching and demonstration experiments, and the phenomenon is not obvious or the experiment process is boring, which cannot stimulate students' interest in experiments, making it difficult to teach Coriolis acceleration theory. At the same time, some experimental instruments have a large str...
