Dynamic collision experiment device

Abstract

The invention relates to a dynamic collision experiment device. A punched spring and a pressure bearing plate are fixedly connected onto a vertical plate at the lower end of a slope railroad shoe, a laser sensor is installed behind the vertical plate, a laser beam of the laser sensor penetrates a through hole in the vertical plate of the slope railroad shoe to the center of the pressure bearing plate, a trolley is arranged at the upper end of the slope railroad shoe, a barrel is arranged in the trolley, a front baffle and a rear end cover are fixedly connected at the front end and the rear end of the trolley in a sealing mode, the trolley is filled with a liquid medium, the front baffle and the outer end face of the barrel are fixedly connected in a sealing mode, a punch rod and a movable piston are arranged in the barrel, an inner hole of the movable piston is connected with the punch rod in a matching mode, the barrel is divided into a front cavity and a rear cavity through the movable piston, a leakage flow hole is formed in a tail cover at the rear end of the rear cavity, the front end of the punch rod is connected with the through hole in the front baffle in a matching mode and in a sealing mode, a main spring is installed on the step cylindrical face of the punch rod and the step cylindrical face of the movable piston, a restoring spring is installed on the rear end step of the movable piston and the rear end face of the tail cover, and the tail cover and the barrel are fixedly connected in a sealing mode.

Description

technical field [0001] The invention relates to a dynamic collision experimental device, in particular to a comprehensive experimental device used in the field of mechanical experiment teaching of theoretical mechanics, engineering mechanics and the like. Background technique [0002] Mechanics is an ancient subject. Its emergence and development process is the deepening process of human beings' understanding of the mechanical motion of objects, and it is further evolved according to its own logic driven by engineering technology. In the branch of solid mechanics, theoretical mechanics is the science that studies the general laws of mechanical motion of objects, specifically the relationship between force and changes in mechanical motion, which is the basis of mechanics and is usually divided into three categories: statics, kinematics, and dynamics. part. The commonly used learning methods of mechanics courses such as theoretical mechanics focus on theoretical teaching and ...

AI Technical Summary

Problems solved by technology

The commonly used learning methods of mechanics courses such as theoretical mechanics focus on theoretical teaching and learning, but lack of experimental teaching links, especially the lack of dynamic comprehensive experimental devices that reflect the relationship between object force and motion changes, so students lack hands-on practice links, which also Does not meet the training requirements of modern engineering applied technical talents
