全地面起重机伸缩主臂的非线性分析及收敛性研究

Non-linear analysis and convergence research on telescopic boom of all-terrain crane

全地面起重机作业时,臂架呈现大变形状态。为得出某真实伸缩主臂的非线性强度解与屈曲解,采用梁单元并加密网格建模,使结果更加精确并得到收敛解,为产品设计过程提供参考。

When all-terrain crane is in operation , the boom indicates big deformation state.To figure out non-linear strength solution and buckling solution of certain actual telescopic boom , beam element and refined net are used for model-ing to get accurate result and the convergence solution , which can provide guidance for product design.
