Portable assembled theoretical mechanics teaching aid

Abstract

The invention discloses a portable assembled theoretical mechanics teaching aid comprising a light flip right-angle hexahedral portable box body. A background motherboard is installed inside a box cover of the box body. The bottom of the box body is divided through PPT plastic filling into a console, an automatic drive device, a teaching aid general parts storage room and a puzzle introduction block placement room. The upper part of the background motherboard is uniformly provided with small circular holes into which pins can be inserted. The lower part of the background motherboard is provided with a horizontal slide on which a walking drive device is installed, and the walking drive device is connected with a transmission device and is connected through a circuit with the console. The portable assembled theoretical mechanics teaching aid has a simple and novel structure and complete functions, is made of good material, and is light. The whole device is installed inside a suitcase and can be easily carried by teachers to the class. Students can assemble the mechanism and control the motion of the mechanism, so that students are inspired to think deeply and further understand the mechanics theory.

Description

technical field [0001] The invention relates to the field of teaching demonstration, in particular to a portable and assembled theoretical mechanics teaching aid. Background technique [0002] In the process of teaching theoretical mechanics, various engineering structures, especially mechanical mechanisms, must be clarified about the motion forms of the rigid bodies in the mechanism and the relationship between motions, so as to analyze the binding force, speed synthesis and decomposition, and acceleration synthesis and decomposition , and dynamics calculations. However, the mechanism is the first time that the students encounter the object. The motion form and relative motion relationship of each rigid body in the mechanism is unimaginable. At present, multimedia animation is widely used to display the movement of various mechanisms, but a plane animation There is no realistic and intuitive thumbnail model of the actual mechanism, which can be touched and operated by the s...

Problems solved by technology

[0002] In the process of teaching theoretical mechanics, various engineering structures, especially mechanical mechanisms, must be clarified about the motion forms of the rigid bodies in the mechanism and the relationship between motions, so as to analyze the binding force, speed synthesis and decomposition, and acceleration synthesis and decomposition , and dynamics calculations. However, the mechanism is the first time that the students encounter the object. The motion form and relative motion relationship of each rigid body in the mechanism is unimaginable. At present, multimedia animation is widely used to display the movement of various mechanisms, but a plane animation There is no actual mechanism. The thumbnail model is realistic and intuitive. It can be touched and operated by the students at will. The students are often confused about the structure and movement of the mechanism.

The physical teaching aids used in the early days are pure steel mechanical teaching aids, which are large in size, heavy in weight, and have a single fixed structure, or wooden teaching aids are large in size, short in life, high in cost, single in function, and cannot be connected to multimedia systems, etc. shortcoming

Can no longer meet the needs of modern teaching
