Design case 2: Reduced Order Modeling of Coupled Systems Reduced Order Model: The dynamic behaviour of the microswitch shown on the previous page was reduced by so-called modal projection techniques. Similar to the Mode Superposition Method known from structural analyses we represent the deformed structure by a weighted combination of eigenmodes. The state variables of the black-box model are based on several response surfaces which are extracted by a series of FE runs. In contrast to early implementations the newly developed tool accounts for >       Structural non-linearities such as the stress stiffening effects >       Coupling effects of electrostatic-structural domains and >       Squeeze and slide film damping in viscose environment Furthermore it provides fully coupled voltage-current ports for each conductor and nodal force-displacement ports at master nodes to model contact problems, to apply nodal forces or to watch true displacement results.
