Topology Optimization Method

In this paper, a parametric structural shape and topology optimization method is presented. To solving structure optimization problems, the level-set method has become a powerful design tool and been widely used in many fields. Combined with the Radial Basis Functions (RBF), which is a popular tool in function approximation, the method of level-set can be represented in a parametric way with a set of advantages comparing with the conventional discrete means. Some numerical examples are presented to illustrate its advantages.

Topology Optimization Method

In this paper, the lightweight design of an aero-engine stator structure is studied as an application case. Different kinds of loading conditions are taken into account. Mathematical formulations of the optimization problem are presented. Two optimization strategies combining shape and topology optimization are tested to get optimal design results.
