Topology Optimization for Eigenvalue Problems in Aerospace Structure Design with Rigid Links

Abstract:

The main purpose of this paper is to present an aerospace engineering application of topology optimization for maximizing eigenvalue problem. In this problem, the internal structure of a rocket which is supposed to support four satellites needs to be designed. To improve the vibration performance of the whole structure, the topology optimization technology is introduced to gain a suitable structure configuration. To simplify the model, satellites are regarded as lumped masses and connecting to their supporting structure with rigid links.
