Abstract:

A method for checking the bonding strength of high-speed Electric Multiple Units （EMU） side window based on residual strength is proposed from the application point of engineering considerations. This method enables to check the bonding strength of the adhesive layer by combination of accelerated aging experiments and simulation analysis. Using the implementation of the program to complete the test results of the display， obtaining the safety margin cloud map of adhesive layer， which is convenient for the engineering staff. Finally， the effectiveness of the method is verified by the actual vehicle model.

Key words: hydrothermal cycle, residual strength, normal-shear ratio, EMU train, safety margin
