摘要

粘接技术是汽车内饰涂层结构的主要连接方式,其工艺和结构都在不断优化。本文采用ABAQUS软件建立了仪表板粘结结构的有限元模型。基于黏聚区模型(CZM)方法,对不同位移加载条件下地表节理的损伤破坏过程进行了数值模拟。从数值计算方法、实验验证和数值结果分析三个方面验证了基于CZM的有限元模型对粘结面接头损伤破坏过程数值模拟的有效性。结果表明,基于CZM理论的有限元模型可以有效地模拟和评价多相聚合物或复合材料表面接头的损伤和破坏过程。通过获取荷载-位移曲线、应力云图和损伤云图,观察和分析了表面节理损伤起裂、损伤演化和破坏的动态过程,并对层间模型的结合强度进行了对比分析。与皮与布的粘接界面相比,框架与布的粘接界面不易损坏。

Effectiveness analysis of the study on the bonding performance of car soft decoration coated interior trim based on cohesive zone model
ABSTRACT Bonding technology is used as the main connection mode of coated structures of car interior trim, of which the process and structure are being continuously optimized. In this paper, ABAQUS software is applied to establish the finite element model of the bonded structure of the dash panel. Based on the cohesive zone model (CZM) method, the damage and failure process of surface joints under different displacement loading conditions are numerically simulated. The effectiveness of the finite element model based on CZM for the numerical simulation of the damage and failure processes of bonded surface joints is verified from the perspectives of the numerical calculation method, experimental verification, and numerical result analysis. The results show that the finite element model based on CZM theory can effectively simulate and evaluate the damage and failure processes of multiphase polymers or composite surface joints. By obtaining the load‒displacement curves, the stress nephogram and the damage nephogram, the dynamic processes of damage initiation, damage evolution and failure of the surface joint are observed and analysed, and the bonding strength of the interlayer model is also compared and analysed. Compared with the bonding interface between the skin and cloth, the bonding interface between the frame and cloth is less prone to damage.
