为了研究偏心缩套缸体的界面应力分布规律，建立了偏心缩套缸体的数学模型，通过工程实例计算与有限元结果对比，结果表明缸体界面压力模型理论值与有限元计算值相吻合。此外，由此数学模型可知偏心缩套缸体界面压力均沿圆周分布不均，且呈减小趋势。
為瞭研究偏心縮套缸體的界麵應力分佈規律，建立瞭偏心縮套缸體的數學模型，通過工程實例計算與有限元結果對比，結果錶明缸體界麵壓力模型理論值與有限元計算值相吻閤。此外，由此數學模型可知偏心縮套缸體界麵壓力均沿圓週分佈不均，且呈減小趨勢。

For studying the interfacial pressure distribution regularity of shrink-fit cylinder with eccentricity,the mathematical model about interfacial pressure of shrink-fit cylinder with eccentricity was established. The theoretical value of the mathematical model was identical with the data of finite element analysis (FEA)by comparing the result that based on an actual project with that of FEA. Beyond that,it is known from the mathematical model that the interfacial pressure of cylinder represents uneven distribution,and de-creases gradually around the circumference.
