摘要/Abstract

摘要：

采用有限元分析方法研究了汽车内饰件胶接过程中不同时刻的温度及位移分布，探究了边界约束对模型温度、热应力、位移及胶层损伤情况的影响。模拟分析结果显示：随着时间的延长，模型的温度升高、位移增大，且在曲率大的位置更加明显；胶接过程中同时对内饰件的侧面和底面进行约束，能够有效减少胶层损伤，提高结构的整体刚度。通过对比不同边界约束下的温度、应力和位移云图，确定同时约束侧面和底面的优化设计对提高汽车内饰件胶接质量的重要性。本文不仅优化了汽车内饰件胶接工艺，而且为提升胶接过程中产品质量提供了指导。

Abstract:

Finite element analysis was used to study the temperature and displacement distribution of automotive interior components at different moments during the bonding process， and the effects of boundary constraints on the model temperature， thermal stress， displacement and damage to the adhesive layer was investigated. The simulation analysis results show that with the increase of time， the temperature of the model increases， the displacement becomes larger and more obvious in the position of large curvature； the simultaneous constraints on the side and bottom surfaces of the interior components during the bonding process effectively reduce the damage of the adhesive layer and improve the overall stiffness of the structure. Comparing the temperature， stress and displacement clound maps under different boundary constraints， it is determined that the optimal design of constraining the side and bottom surfaces at the same time is important for improving the quality of bonding of automotive interior components. This study optimises the bonding process for automotive interior components and provides guidance for improving product quality during the bonding process.

Key words: automotive interior components, finite element analysis, thermal stress analysis, adhesive layer damage, temperature distribution
