An efficient Generalized Geometry Contact algorithm including modal reduction flexible bodies

In the MFBD (Multi-Flexible-Body Dynamics) (RecurDyn, 2017), the contact analysis is very important. To develop the general purpose contact algorithm for rigid and flexible bodies, the Generalized Geometry Contact algorithm, which is called ‘Geo Contact', has been developed by Choi&apos...

To develop the general purpose contact algorithm for rigid and flexible bodies, the Generalized Geometry Contact algorithm, which is called ‘Geo Contact', has been developed by Choi's (Choi et al., 2013), (Choi and Choi, 2012), (Choi, 2009) for the contact problems between the rigid and flexible bodies with the general shaped geometries.

In order to get a flexible body of modal reduction, the CMS (Component Mode Synthesis) analysis of Craig-Bampton's (Craig and Bampton, 1965) is widely used.
