Optimization Design of Mount Container Based on Quality Improvement

In this paper, the cracking quality issues of the mount container were described for a certain military off-road vehicle. Through simulating cracking conditions and checking the structure of the cracked part, the main cause of cracking was determined. Due to the multi-factor characteristics of the container cracking, the ADDOFD method, strain energy analysis, sensitivity analysis and orthogonal test were used to analyze and calculate to determine the optimal solution under various conditional constraints. Through CAE virtual verification and real vehicle test verification, the quality issues of the container cracking were solved. The results can provide a reference for the design and improvement design of the off-road vehicle container.
