Vehicle body damage caused by accidents often presents unique conditions, making it difficult to acquire practical maintenance skills through textbook theory alone. To address this issue, this study explores body repair techniques, including the complete replacement, partial replacement, and modification of side quarter panels, with a focus on preventing depreciation, reducing environmental pollution, and maximizing vehicle owner satisfaction. In particular, the study highlights the need for a standardized body repair manual for vehicles with severe damage to the rear side members caused by rear-end collisions. This manual aims to minimize repair discrepancies due to differences in operator skill levels and proposes a solution to prevent the depreciation of vehicle market value after repairs. The study’s objective is to standardize the repair and replacement of rear side members in vehicle repair shops, ensuring consistent repair quality for consumers and contributing to the preservation of vehicle value.

Vehicle crash analysis a lot of time and manpower in preprocessing for analysis rather than analysis in analytical studies of the situation that is being committed. In this studies involving conflict with an existing automation system of the body is mainly optimized for a particular field, and researchers think that is an inconvenience that can be used in stone until a comprehensive analysis of the bodywork of each study. Therefore, it is very important to development of automotive system for vehicle crash analysis, the research related studies were carried out. In this study, vehicle crash analysis is performed against that can be used for multiple and effectively utilized by system based meshing in an aim to reduce the time and resource that by developing an automotive system. The results of the study, it was possible to construct an automated system the more time consuming mesh generation for vehicle crash analysis.
