摘　　要：附着式升降脚手架为薄壁钢构件组成的框架结构,实际工程应用中受力复杂,其静力承载能力的验算是确保爬架使用安全可靠的前提。考虑两种荷载组合,使用ANSYS有限元软件对正常使用工况及提升工况下的爬架力学性能进行分析,研究其应力、变形等力学性能的演化规律。模拟结果表明:各种荷载组合及工况下爬架应力、位移均处于容许范围内;爬架提升工况下的应力、位移均大于正常工作工况;提出了相应的补强措施,可为实际工程中提高爬架使用的安全稳定性提供参考。The attached lifting scaffold is a frame structure composed of thin-walled steel members,and its stress is complex in practical engineering application.The checking calculation of its static bearing capacity is the premise to ensure the safety and reliability of climbing frame.Considering two kinds of load combination,ANSYS finite element software is used to analyze the mechanical properties of climbing frame under normal working condition and lifting condition,and the evolution law of mechanical properties such as stress and deformation is studied.The simulation results show that:the stress and displacement of the climbing frame under various load combinations and working conditions are within the allowable range,the stress and displacement under the climbing frame lifting condition are greater than the normal working condition,the corresponding reinforcement measures are proposed,which can provide reference for improving the safety and stability of climbing frame in practical engineering.
