Abstract

In this paper, we present a new level set-based topology optimization method targeting dynamic characteristics of rotational symmetry structures. Rotational symmetry struc- tures are used in rolling mechanism, therefore, dynamic characteristics are often impor- tant design criteria. Here, we focus on the lowest eigenfrequency and maximize it based on the level set theory. To guarantee the rotational symmetry of the target structure, we propose to average nodal sensitivities based on the rotational symmetry. We demonstrate the usefulness of our proposed method by a numerical example.
