Abstract: Addressing the gravity sagging problem of front hood assembly in the trial production phase, this paper aims to enhance structural rigidity and improve dimensional quality through optimized design. Leveraging CAE simulation technology and project experience,this paper systematically investigates the root causes of the problem. Three improvement schemes are proposed and comparatively evaluated in terms of cost, implementation timeline, and effectiveness, ultimately identifying an optimal solution that combines cost efficiency with significant performance enhancement. This research not only resolves the sagging problem of front hood assembly but also provides an economical and efficient solution idea for the optimal design of similar gravity sagging defects in automotive manufacturing.
