摘　　要：轴承座在机械领域的运用十分广泛,基于ANSYS软件对轴承座装配体进行强度和变形分析。先通过建立模型、选择单元类型、划分网格、施加边界条件等步骤建立轴承座的有限元模型,再对轴承座进行变形和强度分析,找出结构最易破坏的位置。分析结果表明:轴承座产生的变形主要集中螺栓上和轴承座座体以及底板的连接处,最大等效应力也出现在螺栓中间部位,在筋板与轴承座接触区域存在应力集中。The bearing seat can be widely used in the mechanical field, thus the intensity and distortion analysis for bearingseat assembly is carried out based on the ANSYS software in this paper. At first, the finite element model of bearing seat is established by procedures such as modeling, selecting the unit type, dividing grid, and applying the boundary conditions; then,intensity and distortion analysis of the bearing seat is conducted to find out the most fragile components of the system. The analysis results present that the deformation arising from the bearing seat assembly is mainly on the bolts which connect withbearing seat assembly and the baseboard, with the maximum equivalent stress on the middle part of the bolts, and the stressconcentration exists in the contact area of rib plate and the beating seat.
