有限元优化技术在起重机吊臂结构设计中的应用

Application of the finite element optimization in jib design of the crane

以ANSYS软件为工具,以结构自重为优化目标,以截面尺寸为优化设计变量,以强度、刚度为约束条件,对起重机吊臂进行有限元优化设计,为起重机吊臂的设计和改造提供理论依据。

The writer made a optimization of FEM using ANSYS under the condition, Through regarding the strength and rigidity as restraint, regarding total weigh as object function, regarding the dimension of the section as design variable. Some foundations to crane jib＇s improving and designing was provided.
