Based on ANSYS software, the finite

基于ANSYS软件，建立了塔式起重机整体的有限元模型，分析了塔式起重机臂架的强度和刚度，获得了臂架结构的应力分布，并确定了臂架运行的危险点。与国外的塔式起重机相比，它们具有重量轻，起重能力大，使用寿命长，更换周期清晰等优点。随着我国经济的发展和塔式起重机的大规模应用，国外塔式起重机制造商的进入将不可避免地对国内塔式起重机制造商产生影响。迫切需要提高塔式起重机的设计水平。因此，我希望我的研究能够为塔式起重机的发展做出贡献。

Based on ANSYS software, the finite element model of the entire tower crane was established, the strength and rigidity of the tower crane boom were analyzed, the stress distribution of the boom structure was obtained, and the dangerous points of the boom operation were determined. Compared with foreign tower cranes, they all have the advantages of light weight, large lifting capacity, accurate service life, clear replacement cycle and so on. With the development of my country's economy and the large-scale application of tower cranes, the entry of foreign tower crane manufacturers will inevitably have an impact on domestic tower crane manufacturers. It is urgent to improve the design level of tower cranes. Therefore, I hope that my research can contribute to the development of tower cranes.<br>
