Topological design for minimum dynamic compliance of structures under forced vibration

Abstract

This paper deals with topology optimization of elastic, continuum structures without damping that are subjected to time-harmonic, dynamic loading with prescribed excitation frequency and amplitude. An important objective of such a design problem is often to drive the eigenfrequencies of the structure as far away as possible from the excitation frequency in order to avoid resonance and reduce the vibration level of the structure. The total structural volume, the boundary conditions, and the material are given.
