摘　　要：文中对梯形单元法作了改进，提出了一种计算转子惯性张量的多边形节点分析法。对于任意形状的旋成体，只须标出子午截面上节点的座标和材料密度，即可由文中编制的微机程序算出系统的总质量、形心位置和惯性张量。A nodal analysis method for calculating inertial tensor of rotors is described in this paper. It is developed from and is beter than the trapezoid element method. For bodies of revolution,including those of complicated geometries,the total mass,the location of center and the inertial tensor can be easily determined by using a computer software,provided the coordinates of the nodes on the meridional plane and materials density are given.
