Topology optimization based on the modified optimality criteria method for application to products

In this study, we apply density-based topology optimization using the modified optimality criteria (OC) method to a support yoke. The modified OC method was developed by incorporating the concept of Newton’s method into the OC method. Our proposed method is less dependent on setting the move-limit, so it is employed in the update equation for topology optimization. This paper discusses the effect of the penalization parameter used in the solid isotropic material with penalization method on updates using the modified OC method. We also give a mathematical proof of the convergence properties for the modified OC method.
