Description

technical field [0001] The invention relates to an elastic adhesive fatigue performance testing structure and a manufacturing method thereof, belonging to the technical field of elastic adhesive performance testing. Background technique [0002] With the development of bonding technology, more and more elastic adhesives are used in the production of rail vehicles, and they play a vital role. However, the theoretical basis for the vibration fatigue of elastic adhesives with large elastic modulus is still in the domestic market. There is no specific theoretical and experimental proof for the service life of elastic adhesives, and there are limitations to the aging resistance of elastic adhesives and the application of elastic adhesives. In order to better understand the aging resistance of elastic adhesives and improve the basic theory of elastic adhesive application, it is necessary to simulate the actual operating conditions of vehicles to verify the technical data of elasti...

AI Technical Summary

Problems solved by technology

Due to the large number of vibrations in the fatigue performance test of the elastic adhesive, it needs to reach 1 million times, but the glass surface is smooth, the friction coefficient is small, and the glass substrate is easy to slide during the vibration process, which affects the accuracy of the test results. The glass is fragile under tensile force, inconvenient to use, poor in operability, low in work efficiency, time-consuming and laborious
