Abstract

In this work, a strategy for the model order reduction of large stroke flexure mechanisms is presented. In this, geometrically nonlinear finite element models of each flexible body within the mechanism are projected onto a reduction basis. This basis consists of the body’s Craig-Bampton modes and corresponding modal derivatives. Validation simulations that are performed on commonly used flexure mechanisms show good accuracy of the reduced order models. Therefore, the proposed reduction strategy can be efficiently applied to reduce computational costs of structural optimizations that are required to improve the design of flexure
mechanisms.
