Abstract:
The dynamics of a flexible beam attached to a moving central rigid-body is reported. The system consists of a central rigid-body which can spat ially move and a beam which is attached to the central rigid-body and acted by external acting forces changing inmagnitude and position.The dynamic equations for two-dimensional transverse vibrations of the flexible beam are solved via employing the approach of modal expansion. The dynamic simulation software package resulted from the theory reported in this paper can deal with five different support ing cases. An example is given to validate the method and to analyze the effects of large overall motion on the deformation of the flexible beam.
