摘　　要：本文在正交曲线坐标中建立了一个二十四自由度的壳单元,分析了正交柱壳相贯线上两柱壳的位移与转角并建立了相互转换关系,用主从约束的方法联合求解。几个算例表明,该单元具有较高精度,结果整理简便。用于工程计算可节省大量机时。A 24 degrees of freedom cylindrical element is established in curvilinear coordinates and the displacements transition matrix on intersecting line is for mulated. Some examples show that it is good in accuracy, its results are easy to sort out, and it may save much c. p. u. time in engineering analysis.
