摘　　要：本文基于内聚力模型,提出一种针对柔性屏的贴附方式,克服了传统的屏幕贴附技术只能适用于直面屏贴合而无法贴合柔性材料的问题。通过建立仿真模型对贴合过程进行模拟并分析该过程的应力变化。讨论了仿真模型中不同的下压载荷、旋转速度、材料属性对仿真结果的影响。实验结果表明,基于内聚力模型理论可建立一种针对柔性屏幕的贴合方式。下压载荷的增加将导致薄膜所受应力增大,而旋转速度的变化对应力的影响较小。材料属性对仿真成功与否起着关键因素。Based on the theory of cohesive force model,this paper proposes a flexible screen adhesion method,which overcomes the problem that the traditional screen adhesion technology can only be used for flat screen adhesion but not flexible material adhesion.A simulation model is established to simulate the bonding process and analyze the stress variation of the process.The influence of different down loading and rotation speed on the simulation results is discussed.Based on the cohesion model theory,a kind of fitting method for flexible screen can be established.The influence of the change of the down load on the stress is linear.The change of rotation speed has little effect on stress.
