用有限元法对含有平板式结合面的结构进行分析时，平板本身对结合面层的影响往往会被忽略，误差也由此产生。针对这种平板结合面刚度的传统计算方法的缺陷进行修正，综合考虑结合面层和结合面板两者的弹性，推导出平板式结合面的综合单元刚度矩阵。此刚度矩阵能应用于结合面的有限元计算及动态参数识别当中。通过算例将这种方法与传统方法进行对比验证，前者具有更高的精确度和可靠性。该方法可应用于此类结构的精确建模与分析，为解决其振动问题提供手段。

When FEM is used to analyze the structures that include plate-like joint interfaces, the effect of plates on joint interfaces is often be ignored and defect thus follows. Aiming at the traditional method for calculating the stiffness of plate-like joint, this defect is revised and a comprehensive unit stiffness matrix is deduced. The matrix can be applied to finite element analysis and identities of dynamic characteristic parameters of joint interfaces. By comparing the results of presented method and the traditional method through an example, the former is proven to have higher accuracy and reliability. The presented method can be applied to modeling and analyzing of the similar structure and can be used as a way to solve mechanical vibration issues.
