摘　　要：结合目前企业对立柱质量的实际要求,采用对立柱进行内外混合加载的动态试验模式,并以此为基础,从数学角度考虑在外加载时对立柱进行垂直加载和有角度(锐角)加载,并用ANSYS软件进行仿真分析,通过最大等效应力数据得出需要垂直外加载才能满足试验要求。Combined with the actual needs of enterprise for the column quality, the dynamic test mode of internal and external mixed loading on the column was adopted, and on this basis, considered from the mathematical point of view, vertical loading and angular(acute angle) loading were carried out on the column during external loading. ANSYS software was used for simulation analysis. Through the maximum equivalent stress data, it is concluded that vertical external loading is required to meet the test requirements.
