摘要: |
针对天线座加工过程中两个关键工序的编制主要凭经验,没有进行量化的工艺难题,采用有限元技术分析了装夹方式和夹紧力大小对零件加工变形的影响,得到了基于有限元仿真分析的变形结果,解释了以往加工定位基准选择及装夹合理的原因。根据分析结果,提出了工序改进方法,并给出了加工时对应位置的检测范围,为工艺的编制和生产的顺利进行提供了有利依据。 |

Abstract: |
In antenna mounting process, the organization of the two key working procedures mostly bases on experiences rather than on quantification. Finite element technology is adopted to analyze the influences of fixing manner and clamp power on machining deformation. The deformation results based on finite element simulation analysis explain the reason of eligible machining before. It put forward the improving methods of working procedure, and presents the examination range of corresponding position in machining, which provide available basis for technical organization and production . |
