A demonstration device for gyroscope characteristics

Abstract

A gyroscope character demonstrating device mainly comprises a gyroscope rotor, a driving motor, an inner frame, an outer frame, an inner frame rotating shaft, an outer frame rotating shaft, a base, an elastic pressing sheet, power supplying sliding rings, an angle dial and a power supplying circuit. The gyroscope rotor is fixedly connected with a driving motor rotating shaft. A shell of the driving motor is fixedly connected with the inner frame. The inner frame and the outer frame are connected through one rotating shaft, and the outer frame and the base are connected through one rotating shaft. The inner frame and the outer frame are provided with circular holes. The inner frame rotating shaft and the outer frame rotating shaft are provided with the elastic pressing sheet and pointer scribing lines. The two sides of the outer frame and the two sides of the base are provided with the power supplying sliding rings fixedly connected with the angle dial. The motor is connected with the power supplying circuit through the sliding rings, the inner frame and the outer frame can rotate in all directions, and the rotating angle, displayed on the angle dial, of the inner frame and the outer frame can be read through a pointer. According to the gyroscope character demonstrating device, the motor is connected with a power source through the sliding rings, the two-freedom-degree and all-direction rotation of the two-freedom-degree gyroscope can be achieved, and the character of the gyroscope can be visually demonstrated and quantitatively calculated through the rotated angle, read through the angle dial, of the frames.

Description

technical field [0001] The invention relates to a gyroscope characteristic demonstration device. Aiming at the characteristics of a two-degree-of-freedom gyroscope, it can not only demonstrate visually and qualitatively, but also perform quantitative calculations based on formulas, and compare experimental phenomena theoretically and experimentally. It belongs to the technical field of inertia and can be used for Gyro feature learning and teaching demonstration. Background technique [0002] Gyroscope is the core component in the field of inertial navigation, mastering and understanding the characteristics of gyroscope is the prerequisite for learning habitual technology.

Problems solved by technology

The two-degree-of-freedom gyroscope is a typical gyroscope, which has three characteristics of fixed axis, precession and gyro moment effect. It is an important teaching content in the "inertial technology" course. The teaching content of this part of the course is relatively abstract. Students Difficult to understand, often leads to unclear concept of gyro characteristics, poor grasp, and lays hidden dangers for further learning of subsequent inertial technology

At present, the gyro teaching equipment existing on the market is often due to the unreasonable design and installation of the motor circuit, so that the two-degree-of-freedom gyroscope teaching equipment cannot realize two-degree-of-freedom omni-directional rotation, which is significantly different from the real gyroscope; Students quantitatively calculate the experimental results through the gyroscope characteristic teaching equipment, which cannot make students feel the meaning of the gyroscope characteristic formula through the comparison of theory and experiment. It is not helpful for students to understand the theoretical formula of gyroscope characteristics, and the demonstration effect is not good
