공차해석을 위한 조립공정 시뮬레이션 알고리즘의 연구 및 사례

As the customers’ expectation level for product quality rises, careful tolerance design gains increasing importance. Successful tolerance design still requires iterative runs of tolerance analyses. Therefore, accurate tolerance analysis or simulation is crucial for enhanced product quality. This paper outlines fundamental algorithms that consist of assembly simulation for tolerance analysis, which includes those for 3-2-1 assembly, axial move, and various types of pattern move. These algorithms have been verified and validated for many basic problems, and some simple cases are illustrated in this paper. Utilizing such algorithms for accurate tolerance analyses will lead to improved product quality in the future.
