摘要
传统柔性件装配偏差分析模型未考虑实际装配过程中装配体下架对装配偏差的影响。利用总体刚度矩阵构建装配偏差力学模型,通过曲面配准技术模拟装配夹具完全释放后的装配体形态,进而求解装配体的装配偏差,并通过飞机壁板件模型进行仿真实验,验证"装配夹具完全释放"对于装配体装配偏差分析的必要性。
In the traditional assembly deviation analysis model of flexible parts.The influence of assembly fixture release on assembly deviation is not considered in actual assembly process.In this paper,the mechanical model of assembly deviation is constructed by using the overall stiffness matrix,and the assembly shape is simulated by the surface registration technology after the assembly fixture is completely released,then the assembly deviation is solved.By the simulation experiment of the aircraft panel model,the necessity for the assembly deviation analysis after the complete release of the assembly fixture is verified.
