[摘要] 針對(duì)大型吊車桁架結(jié)構(gòu)的角節(jié)點(diǎn)，運(yùn)用實(shí)體建模軟件SOLIDWORKS建立桁架結(jié)構(gòu)角節(jié)點(diǎn)的參數(shù)化實(shí)體模型，借助有限元分析軟件ANSYS對(duì)此桁架節(jié)點(diǎn)進(jìn)行了優(yōu)化分析，得到了節(jié)點(diǎn)板各參數(shù)變化對(duì)節(jié)點(diǎn)板應(yīng)力的影響，為節(jié)點(diǎn)設(shè)計(jì)提供參考依據(jù)。

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.
Keywords: parametric; finite element method; optimization
