摘　　要：由伸缩主臂、格构式变幅副臂、超起装置、拉索等组成的组合臂架是全地面起重机一种典型的配置,为简化组合臂架系统分析的建模过程,提出一种基于有限元软件的简化计算方法。基于等效惯性矩法,将格构式副臂等效为实腹式结构,建立实际组合臂架结构和等效后的简化结构,并对两种结构进行几何非线性分析。分析结果表明,本文提出的全地面起重机组合臂架系统几何非线性分析的简化分析方法可有效提高全地面起重机组合臂架设计计算的效率。The composite boom,which is composed of telescopic main boom,lattice-type variable amplitude sub-boom,the up device and cable,is a typical configuration of all-ground crane.In order to simplify the modeling process of the composite boom system analysis,a simplified calculation method based on finite element software is proposed.Based on the method of equivalent moment of inertia,the lattice sub-arm is equivalent to the solid belly structure,and the actual composite arm structure and the simplified structure after the equivalent structure are established,and the geometric nonlinear analysis of the two structures is carried out.The analysis results show that the simplified analysis method of geometric nonlinear analysis of the all-terrain crane combined boom system proposed in this paper can effectively improve the efficiency of the design and calculation of the all-terrain crane combined boom.
