Abstract

This research focuses on the strength analysis and optimized design of the body structure of heavy engineering rescue vehicles. First, a detailed study of the existing body structure was conducted to identify potential weaknesses and problems under real-world operating conditions. Finite element analysis was then employed to evaluate the structural strength, pinpointing critical stress concentration areas and structural flaws. Based on the diagnostic results, improved design schemes were proposed to enhance overall strength and reliability, including measures such as adjusting material distribution and optimizing connection methods. After completing the improved design, experimental verification and performance testing were conducted to confirm the effectiveness of the proposed solutions in terms of load-bearing capacity, deformation resistance, and fatigue life. The findings demonstrate significant performance improvements in the optimized body structure, making it better suited for practical rescue missions. This study provides both theoretical and practical guidance for the design of engineering rescue vehicles and offers valuable insights for the optimization of similar engineering structures.
