摘　　要：桅杆式起重机的后铰座承受巨大的上拔力,是设备与混凝土基础可靠连接的关键。文中通过分析1200 t桅杆式起重机的总体布置和铰座基础的受力,对比不同设计标准中的螺栓计算方法,探讨了该起重机后铰座预埋螺栓的工程计算方法。通过Creo和Ansys的联合应用,快速计算不同刚度铰座匹配不同法兰厚度(螺栓夹持长度)的预埋螺栓,以及预埋螺栓采用不同预紧力时的螺栓群受力分布。对比研究上述不同计算模型的计算结果,发现了铰座刚度和法兰厚度(螺栓夹持长度)对预埋螺栓群受力分布的影响,并对比工程计算结果,提出采用类似工程计算方法时应注意铰座刚度与法兰厚度(螺栓夹持长度)的匹配,为类似大型铰座基础的设计提供一定的参考。The rear hinged seat of a mast crane,which endures substantial uplift forces,is pivotal to the reliable connection between machine and concrete foundation.By examining the general layout of a 1,200t mast crane,the stress at the hinge base was analyzed,bolt calculation methods across various design standards were compared and the engineering calculation methods for embedded bolts in rear hinged base were discussed.Through the combination of Creo and Ansys,the embedded bolts with varying stiffness in hinged seats and different flange thicknesses(bolt clamping lengths)were calculated swiftly.Additionally,the force distribution of embedded bolts with different pre-tightening forces was assessed.By analyzing the calculation results from various models,the influence of hinged seat stiffness and flange thickness(bolt clamping length)on the stress distribution within embedded bolts was identified.Through a comparison of engineering calculation outcomes,suggestions on paying attention to the compatibility of hinged seat stiffness and flange thickness when employing similar engineering calculation methodologies are given.This study can serve as a reference for the design of large hinged seat foundations in similar projects.
