| 摘 要： | 文中针对确定各零部件几何误差对装配精度的影响以及瓶颈装配工序等重要问题,分析了两零件装配时由于配合面表面形貌所导致的几何误差造成的零件位姿变动,确定单工序的配合误差.以此为基础,基于多体系统理论建立多工序装配过程误差传递模型,用矩阵微分法建立了几何误差对装配精度的灵敏度分析模型.该模型可以识别出多工序装配过程中对装配精度有较大影响的主要零部件几何误差,从而为精密装配精度分析以及控制提供基础,并通过实例验证了模型及分析方法的有效性.

| Abstract: | In the process of multistage precision assembly, geometric error of parts is one of the important factors influencing on the assembly precision, and the method to determine the geometric error''s influence and the bottleneck assembly are the primary problems. In this paper, the pose change of the parts was analyzed to concern the mating surface geometric error caused by surface topography in two parts assembly, and to determine the mating error of the single process.Based on the multi-body system theory, an error transformation model of multistage assembly process was established; and then, a sensitivity analysis model of the assembly precision was built with matrix differential method to identify the main geometric errors for the assembly system. The method provides theoretical basis for precision assembly accuracy analysis and control. Finally, an example was presented to validate the established model. |
