Aiming at the problem of buckling stability capability of box section hoist boom of wheel crane, a complete section of hoist boom is taken as analysis object and buckling instability of the webs is analyzed and researched with the booms of different sectional shapes by applying finite element analysis method. Compared with crane design code (GB3811-83), one piece of plate is taken to calculate buckling stability, the method is easier and more accurate and calculation and analysis of complicated sectional shapes are easy to conduct.

针对轮式起重机箱型起重臂的抗屈曲失稳能力问题，采用有限元分析方法，取起重臂截面半波长段作为分析对象，对相同工况不同截面形状的起重臂的屈曲失稳情况进行分析研究，相对于起重机设计规范(GB3811-83)给出的取一块板进行屈曲计算要快捷、准确得多，而且也容易完成对复杂形状截面的计算分析。

According to practical work condition, section of a three segment hoist boom is self-determined with SECWRITE commands, then a finite element model is directly established in ANSYS environment with ANSYS finite element analysis software. Using Beam44 beam unit and node degree of freedom coupling technique to simulate connecting between each boom section and conduct finite element analysis, calculated result of stress deformation for the boom is obtained. The result from digital simulation is in relative coincidence with theoretical analytic result and the nonlinear decline occurrence in boom bending moment curve is explained.

以ANSYS有限元分析软件为工具，按吊臂实际工况，运用SECWRITE命令自定义三节吊臂截面直接在ANSYS环境下创建有限元模型，使用Beam44梁单元和节点自由度耦合技术模拟各节臂的连接，进行有限元分析，得到吊臂应力变形数值计算结果，数值模拟所得结果与理论解析解相吻合，解释吊臂弯矩图出现非线性下降的原因。
