摘　　要：对4种不同直径的螺钉联接结构用有限元分析方法进行了计算和试验研究;对现有螺钉柔度计算方法进行了分析。结果表明,有限元分析计算与试验结果吻合较好;对于被联接件的柔度计算,总结出被联接件长宽比与对柔度的影响β值呈线性关系。Using the f＇mite element method, calculation and test are conducted on the bolted joints of four different diameters, and the existing calculation method for bolt compliance coefficient is analyzed. The results indicate that the calculated and test results by finite element method are agreed well, and value D/tf and β have a linear relation.
