摘要:

以超高层导架爬升式升降工作平台为研究对象，运用集中质量法建立五自由度系统动力学模型并获得其固有频率。对比 ＡＮＳＹＳ有限元仿真所得到的结果，证明建立的五自由度系统动力学模型能够快速地计算系统的低阶频率，可以满足工程的需要。综合 ＡＮＳＹＳ有限元软件对作业平台进行的静力学分析、模态分析和随机振动分析，得到最大变形值和最大应力值及发生的位置。作业平台在实际运行过程中，应尽量避开低阶频率，防止发生共振造成破坏。采取必要的措施，可以减小护栏的变形量和护栏连接处的应力。

Abstract:

Taking the super high-rise guide frame climbing lifting platform as the research object, the five-degree-of-freedom system dynamics model was established by the centralized mass method and its natural frequency was obtained. Comparing the results obtained by ANSYS finite element simulation, it is proved that the established five-degree-of-freedom system dynamics model can quickly calculate the low-order frequency of the system and meet the needs of engineering. The ANSYS finite element software was used to conduct the static analysis, modal analysis and random vibration of the working platform to obtain the maximum deformation value and the maximum stress value and the location of the occurrence. During the actual operation of the working platform, the low-order frequency should be avoided as much as possible to prevent the resonance from causing damage. The necessary measures can be taken to reduce the amount of deformation of the guardrail and the stress at the joint of the guardrail.
