摘　　要：强度和振动特性是设计塔式起重机的金属结构的重要指标。利用有限单元法进行塔式起重机的整体建模,分析了塔式起重机的强度特性和振动特性,指出了极限吊重情况下静态极限强度的位置,并分析了塔式起重机的振动频率和振型,为研究塔式起重机的其他动力响应提供了依据。Strength and vibration are important parameters in the design of tower crane. Ensemble modeling of tower crane is carried out in this paper through finite element method. Based on this model, strength character and vibration character are analyzed. Position of limit strength also vibration frequency and shape are brought forward, which offers a foundation for studies on other responses to dynamics of tower crane.
