Structural optimization and stiffness analysis of truss frame
In this article,the finite-element model is set up for the parametric analysis on the truss frame;both the topology optimization and the multi-objective optimization are carried out;the optimized frame's stress and stiffness are analyzed,and the results obtained from the stiffness analysis are verified by experiments.Firstly,efforts are made to set up the model of the truss frame,and ANSYS is used for the frame's topology design,in order to work out the optimization model.At the same time,with the focus on the frame's key stress parts,the multi-objective optimization,and the weight of the frame reduces by 0.82 kg after optimization.According to the actual competition field and running conditions,the analysis is conducted on the frame's stress un-der specific working conditions.On this basis,efforts are made to explore the frame's bending and torsional stiffness.In combi-nation with the confirmatory experiment,the frame's torsional stiffness is emphatically analyzed.It is verified that the truss frame has excellent comprehensive mechanical properties.
