In this paper,the influence of surface temperature on the strength of contact surface is investigated based on the influence of displacement on the quality of overmolded products by simulation software.In the process of research,the model is coupled with temperature and displacement,the loading mode is unchanged,and the temperature and loading displacement are changed.Through comparison,it is found that the simulation results of different displacements have similar characteristics under the same temperature difference.The decrease of temperature will accelerate the damage and failure of adhesive layer,and the value of failure load will increase;Increasing temperature will promote the initial damage of adhesive layer,but delay the failure of adhesive layer and reduce the value of failure load.The increase and decrease of temperature will cause the change of stress,and the change trend is gradually increasing from inside to outside.The peeling force is provided by displacement load and stress in the loading process.
