Industry Internship: Tolerance Study on Automotive Part Assembly

本研究的目的是研究一种基于期望产品规格和已知制造过程可变性的设计数学公差分配方法。分配标准将与VSA（变异模拟分析）商业软件包中使用的基于蒙特卡罗统计方法的容差分析进行比较。一旦理解了分布是如何组合在一起的，一个正式的容差分配方法就完成了。与在VSA软件上进行的“假设”测试相反，这种方法是预先确定允许的零件公差的更经验的方法

The objective of this research is to investigate a mathematical tolerance allocation approach for design based on desired product specification and known manufacturing process variability. The allocation criteria will be compared to the tolerance analysis based on Monte Carlo statistical methods used in the VSA (Variation Simulation Analysis) commercial package. Once it is understood how the distributions are combined, a formal tolerance allocation methodology will then be completed. This approach is a more empirical approach of pre-determining allowable part tolerance as opposed to the "what-if" tests conducted on the VSA software
