摘　　要：对土工离心机超重机器人的重要部件-Y轴横梁进行了有限元分析。采用三维十节点四面体结构实体单元进行网格的划分,得到20888个单元和43220节点的有限元模型。计算了Y轴横梁在不同离心惯性力作用下168种工况的变形,考虑了离心惯性力方向的影响,得到机器人在受到不同离心惯性力时横梁的变形图。Y梐xial-beam fixing geotechnical centrifuge overweighted robot is analysed with finite element method in this paper and meshed with 3D 10 - node tetrahedral structural solid into 20888 elements and 43220 nodes finite element model. It is calculated that the deformation of 168 types of operating modes under different centrifugal inertial force and is considered the effectof centrifugal inertial force in directin. Data from the calculation is fitted Y - axial - beam deformation pattern when structure is loaded with different centrifugal inertial force.
