Abstract:
The stress of different adhesive bodies were simulated and analyzed at different temperature, and the thermal expansion coefficient of different metals were tested by the Thermal Expansion Instrument. Then, the metals with different thermal expansion coefficient were bonded to the glass separately, then the adhesive bodies were heated in a semi-enclosed space and their deformation were measured by Hartmann. The results show that the simulation data of the adhesive bodies agree well with the experiment data. It can be used to guide the design of thermal expansion matching for different attributes materials.
