基于质量问题改善的悬置货箱优化设计

通过介绍某型军用越野汽车悬置货箱开裂质量问题，模拟分析开裂工况，对开裂部位结构检查确定引起开裂的主因，基于该货箱开裂多问题多因素的特点，使用平均驱动自由度位移法、应变能分析、敏感度分析、正交试验法等方法进行分析计算，在各种条件约束下确定最优的改善方案.通过CAE虚拟验证和实车验证最终解决了货箱开裂问题.为越野汽车货箱的设计及设计改进提供了参考.

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.
