摘　　要：本文运用弹性模态理论,并通过胡克定律推导出了电梯曳引钢丝绳系统固有频率计算公式。本文分析了青岛市某小区旧楼加装电梯,建立了绕绳比为2:1的电梯曳引钢丝绳结构模型。通过模态分析,得出了在固定载荷情况下电梯运行至不同楼层时曳引钢丝绳的固有频率,从而对电梯运行过程中的振动情况进行探讨。By using the elastic mode theory and Hooke's law,the calculation formula for the natural frequency of the elevator traction wire rope system was derived in this paper.An analysis was conducted of the elevator in an old building in a residential area in Qingdao,and a structural model of the elevator traction wire rope with a rope ratio of 2:1 was established.Through modal analysis,the natural frequency of the traction wire rope when the elevator runs to different floors under fixed load conditions was obtained,thus exploring the vibration during elevator running.
