Description

technical field [0001] The invention relates to the field of adhesive bonding reliability experiments, in particular to an adhesive bonding reliability experimental device and an experimental method for simulating a transverse vibration working condition. Background technique [0002] Adhesive bonding technology is widely used in the connection and sealing of various contact surfaces. It has the characteristics of reliable connection and good sealing performance. It is widely used in the actual production of aircraft and automobiles. Especially, in the assembly process of the engine, the glue is widely used for the sealing of the two processed surfaces, which affects the sealing and safety of the engine. Adhesive reliability is a key index to measure the performance of the engine's adhesive seal. Failure of the adhesive seal will cause leakage. Improving the adhesive seal of the machined surface is of great significance to ensure the service performance of the engine. [00...
