基于ANSYS的桁架悬臂梁结构优化设计

his article uses the ANSYS finite element analysis software parametric design language to establish truss finite element model of cantilever beam, then making the truss girder of the cantilever beam and secondary beam cross section shapes and sizes as design variables, and using the volume of the cantilever beam as target function, considering the strength, stiffness of the beam truss and section size constraints, with zero order optimization method, to optimize the girder cantilever beam structure. Through the optimization analysis, it obtained the reasonable structure shape and size. The research results show that through the optimization analysis, the truss cantilever beam can save a lot of engineering materials under the satisfying engineering demand.
