[摘要] 针对大型吊车桁架结构的角节点，运用实体建模软件SOLIDWORKS建立桁架结构角节点的参数化实体模型，借助有限元分析软件ANSYS对此桁架节点进行了优化分析，得到了节点板各参数变化对节点板应力的影响，为节点设计提供参考依据。

Abstract: In view oflarge crane corner node of truss structure, parametric solid model of the corner node was established by the software SOLIDWORKS. Based on the optimal analysis by the FEM software ANSYS, each parameter change on the impact of gusset plate stress was obtained, and which can be regard as the reference on design of truss node.
