(mentor) Faculty Mechanical, Maritime and Materials Engineering Department Precision and Microsystems Engineering Programme Engineering Mechanics Date 2014-06-27 Abstract In high precision motion systems, rather flexible cable slabs provide electrical power and cooling liquid to moving stages. The positioning accuracy of free floating stages is defined by the disturbances action on it. So, it is of utmost importance to accurately quantify the disturbance forces of these cables. The mathematical model of such a structure must feature geometric nonlinearities. The computational cost of such a model is often prohibitive, therefore nonlinear reduction techniques are needed. This contribution introduces a newly developed reduction technique known as the Generalized Craig Bampton (GCB) method which is an extension of the well-known Craig Bampton reduction technique, applicable to finite deformations. The GCB expressions are integrated using a two stage offline-online integration scheme which achieves near real time simulation during the online stage. The method is compared with both the fully nonlinear model and experimental results and is seen to show a good agreement with both.
