基于ANSYS Workbench变截面压杆屈曲分析方法

摘要

Taking the variable cross-section compressive bar as an example, the concept modeling in ANSYS Workbench has been adopted to set up 3D modeling. Constraints have been enacted to both sides of the bar as per the actual application condition. The critical bending load of the variable cross-section has been calculated by enacting unit load from buckling analysis module of ANSYS Workbench.%以工程应用中变截面压杆为例,运用ANSYS Workbench中概念建模方法进行3D建模,根据实际应用条件对压杆两端施加约束,在ANSYS Workbench的屈曲分析模块中通过施加单位载荷计算出变截面压杆临界弯曲载荷.
