摘　　要：根据某公司提供的升降施工平台结构尺寸,利用ANSA和ANSYS软件接口,采用精度较高的三维实体单元准确建立施工升降平台结构的有限元模型,并对其进行4种工况下结构的安全校核模拟计算。计算结果表明,工况1、3和工况2、4下作用载荷成线性,仅需考虑最危险载荷工况3和工况4;任意工况下升降施工平台最危险位置发生在风载作用的顶部网框横杆与竖杆焊接处,计算结果符合强度要求。分析结果可为施工平台的结构设计与改进提供参考依据。Finite Element Method(FEM)is used to analyse the mechanical performance of the construction lifting platform based on its structural and loading characteristics.The finite element model of its structure is eatablished by using 3-D solid element and its stress distribution graph in four working conditions is calculated by interface between ANSA and ANSYS.The analysis result indicates that the load under 1st and 2nd working conditions is directly proportional to the load under 3rd and 4th working conditions,but 3rd and 4th working conditions are regarded as the most dangerous ones.The most dangerous position of the construction lifting platform is at the welding position between crossbars and vertical bars of top screen frame.The analysis result can be used as reference for the structural design and improvement of the construction lifting platform.
