为研究汽车制造装配中汽车引擎盖的匹配过程，文中基于有限元分析的虚拟环境，搭建了引擎盖的外综合样架匹配虚拟模型，并通过不同力学因素条件的对比分析以及调整元件的参数敏感性分析，得到了重力和弹性调整元件变形对引擎盖匹配的影响，以及调整元件参数调整值对各个基准点位置偏差值的敏感性，最后结合多目标优化方法，提出了一种考虑重力和弹性调整元件变形的引擎盖快速匹配调整策略，并成功应用于汽车虚拟匹配中。仿真与试验结果表明该策略可以有效地减少装配调整成本和提高调整效率。

Based on the virtual environment of finite element analysis，a virtual model for the automobile hood matching was constructed to study the matching process in automobile manufacturing and assembly． The influence of gravity and the deformation of elastic adjusting elements on the matching process was clarified through the com-parative analysis of different mechanical factors and the sensitivity analysis of the parameters of the adjusting ele-ments． And the sensitivity of the adjusting elements’parameters to the position deviation of each reference point was obtained． Finally，a fast adjustment strategy for the automobile hood matching considering the deformation of gravity and elastic adjustment elements was proposed by combining the analysis results and the multi-objective opti-mization method． The strategy was successfully applied to the virtual matching of automobile hood，and the simula-tion and experimental results show that this strategy can effectively reduce the cost of adjustment assembly and im-prove the adjustment efficiency．
