钣金件广泛应用于汽车车身和飞机车身。针对影响系数法不能准确分析零件偏差与装配偏差之间关系的问题，提出了一种基于功率平衡法的钣金零件偏差分析模型。根据“4-2-1”原理将简单金属平面加载到夹具上，分析了装配过程中零件的各种偏差。分析表明，在焊接过程中，焊枪做相同的功。在此基础上，建立了零件偏差与装配偏差之间的敏感系数矩阵。最后以两个Z形钣金件为例说明了装配误差分析过程，结果表明了功率平衡法的准确性。
Sheet metal parts are widely used in auto body and airplane body. As the method of influence coefficient cannot accurately analyze the relationship between part deviations and assembly variations, this paper proposes a new variation analysis model based on a method of power balance for sheet metal parts. The simple metal planes are loaded to fixtures according to the principle of “4-2-1”; and then variety of part deviations is analyzed during assembly process. The analysis shows that the welding guns do same work during welding process. Based on the above, this work establishes sensitive coefficient matrices between part deviations and assembly variations. Finally, two Z-shape sheet metal parts illustrate the assembling variation analysis process and the results indicate the accuracy of the method of power balance.
