Optimization design of guide wheel's structure parameters based on MATLAB
In this article,based on the TVR-typed double-rim single-wheel guide system,efforts are made to explore the guide wheel's optimal structure,with the goal of lightweight to meet the strength requirements under both straight and curved working conditions.The objective function is worked out with the guide wheel's lightweight as the optimization objective;the mathematical model is set up with its sufficient strength and rigidity as the constraint conditions.The code is formulated in MAT-LAB;the SQP and Interior Point algorithms are used to solve the mathematical model.The finite-element analytical model is con-structed with the guide wheel's structure parameters obtained by means of different optimization algorithms,and the statics simu-lation is carried out under the specific working conditions in the finite-element analytical software Workbench.The results show that thanks to the Interior Point algorithm,the guide wheel's optimized parameters such as rigidity and strength meet the related requirements;it is verified that these parameters which are effective for the guide wheel's structure optimization ensure a high standard of lightweight design.
