摘　　要：对塔式起重机整体有限元结构分析与评定方法进行了研究,给出了总体分析思路和主要步骤。探讨了有限元模型建立中结构简化、离散及边界条件的施加方法,建立了参数化分析系统,对各功能模块的实现细节进行了讨论。使用建立的分析系统对某塔机进行整体有限元分析,对起重臂的初步设计结构进行了评定。The finite element structural analysis method for the whole structure of the tower crane is studied(?) The overall analysis strategy and the key steps are given. The simplification of the structure, the construction of the analysis model and the imposition of boundary conditions are discussed. A parametric analysis system is built based on the proposed scheme and the inplementation details of each module are presented. The finite element structural analysis of the whole structure of a certain tower crane is carried out and the preliminary design of the jib is verified using the parametric system.
