Abstract

The perceived quality of the whole vehicle is a core issue that car companies are currently focusing on, and dimensional engineering is a key factor affecting its quality. The interior and exterior trims of a car will produce slight deformations due to the influence of ambient temperature, causing changes in the matching dimensions of the interior trims, and placing higher requirements on the consistency of the quality of automobile products. This article analyzes the deformation mechanism of typical parts at different temperatures, combines dimensional engineering technology, reveals the influence of temperature on the gaps of the interior trims of the whole vehicle, and measures the dynamic changes of the gaps and face differences of the test pieces during temperature changes through actual tests, providing a theoretical basis for the dimensional engineering design of automotive interior and exterior trims, while providing practical experience references for product design, development and quality improvement, helping to predict problems in the early stages of design, and creating products with higher quality standards through collaboration in all aspects of production and manufacturing.
