摘　　要：以某塔式起重机金属结构为研究对象,利用有限元软件ANSYS对其金属结构的自振特性进行分析,通过模态分析获取该结构的自振频率及振型。通过分析得出了该塔式起重机金属结构在非工作状态下的前六阶固有频率和各阶模态表现,研究结果为该塔式起重机金属结构的动力学优化提供了理论基础。The free vibration characteristics of metal structure of the tower crane was analyzed by using the finite element software ANSYS. The natural frequencies and modes of the structure were obtained by modal analysis. Through analysis, the first six natural frequencies of the metal structure of the tower crane under non-working conditions and the modal performance of each order were obtained. The research results provide a theoretical basis for the dynamic optimization of the metal structure of tower crane.
