Teaching demonstration device for engineering mechanics

Abstract

The invention provides a teaching demonstration device for engineering mechanics. The teaching demonstration device comprises a base, a support frame fixed to the base, a simulation slideway, a measurement assembly, an automatic ball feeding mechanism, a sliding seat, a detection assembly, a transverse moving electronic scale and an collecting and calculating device. One end of the simulation slideway is rotationally mounted at the edge of the support frame, and the other end is rotationally connected with a lifting mechanism; the measurement assembly is connected between the simulation slideway and the support frame and is used for measuring the rotation angle of the simulation slideway; the automatic ball feeding mechanism is arranged on the support frame, is close to the lifting end ofthe simulation slideway, and conveys test balls into the simulation slideway; the sliding seat is fixedly arranged on the base and is close to the rotating end of the simulation slideway; the detection assembly is mounted on the sliding seat in a sliding manner; the collecting and calculating device is used for collecting data of the measurement assembly, the detection assembly and the transversemoving electronic scale and calculating to obtain a correlation coefficient K; model demonstration is provided in the teaching process to improve the understanding ability of students, and the students can understand the relationship between the movement track and the collision acting force in practice.

Description

technical field [0001] The invention relates to the field of engineering mechanics teaching demonstration supplies, in particular to a teaching demonstration device for engineering mechanics. Background technique [0002] Engineering Mechanics is a discipline that cultivates the basic theoretical knowledge of mechanics, calculation and experiment ability, and guarantees to be engaged in various engineering (such as machinery, civil engineering, materials, energy, transportation, aviation, ships, water conservancy, chemical industry, etc.) The relevant scientific research, technology development, engineering design and mechanics teaching work are carried out smoothly; especially in the course explanation, what is the relationship between the force generated after the collision of the car and the running track of the car before driving? Teaching purely from theory makes students lack the practice process of carrying out simulation experiments. [0003] As far as the current t...
