Multi-sample rapid bending fatigue experimental device

Abstract

The invention discloses a multi-sample rapid bending fatigue experimental device. The device comprises a crank-rocker mechanism and a dead-point position energy storage component that are mounted on abase. The crank-rocker mechanism comprises a crank, a connecting rod, a rocker, a first fulcrum and a second fulcrum. One end of the crank is rotatably hinged to the first fulcrum, and the other endof the crank is hinged to one end of the connecting rod by a rotating shaft, the other end of the connecting rod is hinged to the middle part of the rocker by a rotating shaft, and the lower end of the rocker is rotatably hinged to the second fulcrum. The dead-point position mechanical energy storage component is disposed on both sides of the second fulcrum, when the rocker rotates to a terminal area of a rotatable stroke, the potential energy of the dead-point position mechanical energy storage component is converted to the kinetic energy of the rocker. The rotating shaft at the hinge joint of the crank and the first fulcrum is connected to the rotating shaft of a motor, and the motor drives the crank to rotate around the shaft. The device provided by the invention greatly reduces the experimental cost and energy consumption, and can reflect the resistance variation in the experimental process, has small volume and wide application, and is suitable for laboratory application.

Description

technical field [0001] The invention relates to the field of flexible material research, in particular to a multi-sample rapid bending fatigue test device. Background technique [0002] The study of flexible materials is a very important part of the field of materials science, and bending fatigue resistance is one of the most important properties of flexible materials.
