چکیده مقاله
In this research, a control feedback system is used to study the free vibration response
of rectangular plate made of magnetostrictive material (MsM) for the first time. A
new trigonometric higher order shear deformation plate theory are utilized and the
results of them are compared with two theories in order to clarify their accuracy and
errors. Pasternak foundation is selected to modelling of elastic medium due to
considering both normal and shears modulus. Also in-plane forces are uniformly
applied on magnetostrictive nano-plate (MsNP) in x and y directions. Nonlocal
motion equations are derived using Hamilton’s principle and solved by differential
quadrature method (DQM) considering different boundary conditions. Results
indicate the effect of various parameters such as aspect ratio, thickness ratio, elastic
medium, compression and tension loads and small scale effect on vibration behaviour
of MsNP especially the controller effect of velocity feedback gain to minimizing the
frequency. These finding can be used to active noise and vibration cancellation
systems in micro and nano smart structures.
