摘　　要：针对新设计的ITER纵场重力支撑结构特点,用ANSYS有限元软件对它建立了有限元模型。采用Block Lanczos方法求出了ITER重力支撑的屈曲特征值。分析结果表明ITER重力支撑不会发生屈曲。为了确保新设计结构的可靠性,初步设计了全尺寸支撑的半原型件拟用来对支撑进行工程受力测试。The 3-D finite element model of the gravity support（GS） for ITER toroidal field was built by ANSYS software according to the new designed GS characteristics.The eigenvalues of the GS system under several load cases were solved using the Block Lanczos method.The results of buckling analysis show that the GS buckling doesn＇t occur and the GS structure is secure.In order to ensure the GS reliability,a preliminary semi-prototype with full size is designed and will be used to engineering test for the new designed GS structure.
