In the present study, the analysis of nonlinear vibration for a simply-supported flexible beam with a constant velocity carrying a moving mass is studied. The amplitude of vibration assumed high and its deformation rate is assumed slow. Due to the high amplitude of vibrations, stretching is created in mid-plane, resulting in, the nonlinear strain-displacement relations is obtained, Thus, Nonlin...

This paper deals with the modeling and control of a special class of single-link flexible arms. These arms consist of flexible massless structures having some masses concentrated at certain points of the beam. In this paper, the dynamic model of such flexible arms is dewloped and some of the control properties are deduced. A robust control scheme to remove the effects of friction in the joins i...

This paper presents a novel unified multibeam satellite system model for the performance analysis of different satellite payloads. The model allows the analysis in terms of Signal to Interference plus Noise Ratio (SINR) and CoChannel Interference (CCI). Specifically we formulate the SINR as a function of the multibeam geometry for a given user location granularity. Furthermore, we apply our mod...

Considerable attention has been devoted to active vibration control using intelligent materials as PZT actuators.

The PZT patches are surface bonded near the fixed end of flexible steel cantilever beam. The dynamic model of the flexible steel can...

The purpose of this paper is control of simply supported flexible core sandwich beam's linear vibration equipped with piezoelectric patches under different loads. The effects of external forces imposed on sandwich beam can be reached to a minimum value by designing an appropriate controller and control the beam's vibration. Three-layer sandwich beam theory is used for analytical modeling of san...
