Abstract

The invention discloses a bonding reliability testing device, especially relates to a bonding reliability testing device of simulating the transverse vibration condition, and brings forward a controlmethod according to actual conditions. The testing device comprises a framework body, a main loading platform, a bonding testing sample piece, a left / right vibration loading platform and a central controller. Vibration generated by the left / right vibration loading platform in the frame body acts on the bonding testing sample piece. The vibration loading platform is driven by a motor, and Z-direction loading of a main loading platform is followed. The control method of the testing device comprises steps of receiving instruction and feeding back information, conducting coordination control of each part of the testing device and the like. Through Z-direction following of the main loading axis and transverse vibration loading of the test piece, tension property testing under the transverse vibration condition is realized. The testing device is more suitable for performance testing in the actual service environment and can be widely applied to tension testing and fatigue testing of bondingreliability testing under transverse vibration condition.

Description

Technical field

[0001] The invention relates to the field of bonding reliability experiments, in particular to a bonding reliability experiment device and an experiment method thereof that simulate lateral vibration working conditions. Background technique

[0002] Gluing technology is widely used in the connection and sealing of various contact surfaces. It has the characteristics of reliable connection and good sealing. It has a very wide range of applications in actual production such as airplanes and automobiles. In particular, in the assembly process of the engine, a large number of glue joints are used to seal the two processed surfaces, which affects the sealing and safety of the engine. Bonding reliability is a key indicator to measure the performance of the engine's bonding and sealing. The failure of the bonding and sealing will cause leakage. Improving the bonding and sealing of the machined surface is of great significance to ensuring the service performance of the en...
