Abstract

The invention relates to the field of automobile glass, in particular, relates to detection of automobile glass, and specifically provides a fatigue testing device for automobile glass. The fatigue testing device comprises a test base, a test support, at least four vibrators, an ultrasonic detection device and a computer. The test support is fixed on the test base, and a containing opening is arranged in a central area of the test support; at least four vibrators are respectively mounted in four corner areas of the containing opening, and at least four vibrators and the ultrasonic detection device are connected to the computer; the ultrasonic detection device can be used for detecting to-be-tested automobile glass, and the computer can control at least four vibrators and obtain detection results of the ultrasonic detection device. The fatigue testing device can truly simulate the installation condition and the driving environment of the automobile glass on an automobile body, so as toimprove the accuracy of fatigue tests; internal cracks and surface cracks of the automobile glass can be simultaneously detected, and the detection results are timely and accurately saved.

Description

technical field [0001] The invention relates to the field of automobile glass, in particular to the detection of automobile glass, and specifically provides a fatigue test device for automobile glass. Background technique [0002] Whether the car is starting or running, due to the unbalanced rotation and reciprocating motion of the moving parts of the engine, the variable gas load of the crankshaft, the inertial force and elastic force of the valve group, the load effect of the meshing gear pair of the transmission, the drive shaft, etc. Factors such as the variable torque of the speed universal joint and the effect of the road surface and non-road surface on the suspension will make the car be in a rather complex vibration environment. As a car ages, some auto parts may experience fatigue damage followed by cracks or fractures. Fatigue refers to the process in which a test piece or component material undergoes crack initiation and propagation under the action of alternatin...
