An efficient semi-numerical framework is used in this paper to analyze the dynamic model of an axially moving beam with a nonlinear attachment composed energy sink and piezoelectric device. The governing equations motion system are derived by using Hamilton’s principle von Karman strain-displacement relation Euler - Bernoulli theory. modeled as lumped mass point mass, spring cubic stiffness lin...

Transverse vibration of two axially moving beams connected by a Winkler elastic foundation is analyzed analytically. The system is a model of paper and paper-cloth (wire-screen) used in paper making. The two beams are tensioned, translating axially with a common constant velocity, simply supported at their ends, and of different materials and geometry. Due to the effect of translation, the dyna...

In this paper, an active vibration control of the translating steel strip in the zinc galvanizing line is investigated. The unwanted vibrations of the strip deteriorate the uniformity of the deposited mass on the surfaces of the steel strip and the consumption of zinc. The translating steel strip is modelled as a moving belt equation by using Hamilton’s principle for the systems with changing m...

The treatment of boron(III) subphthalocyanine chloride with 1,3-bis[3-(diethylamino)phenoxy]propan-2-ol 2 and 2,3-bis[3-(diethylamino)phenoxy]propan-1-ol 4 in toluene gave the corresponding axially substituted boron(III) subphthalocyanine compounds 3 and 5. The novel axially diethylaminophenoxypropanoxy substituted subphthalocyanines were characterized by standard spectroscopy methods. The elec...

The purpose of this paper is to study the effect of presence of fluid within and around a poroelastic circular cylindrical shell of infinite extent on axially symmetric vibrations. The frequency equation each for a pervious and an impervious surface is obtained employing Biot’s theory. Radial vibrations and axially symmetric shear vibrations are uncoupled when the wavenumber is vanished. The pr...

We consider a vector field in a half-space which vanishes at . If a vector field is invariant under rotation around axis, we say that it is axially symmetric, in other words, for every rotation about the axis. If, moreover, an axially symmetric vector field is invariant under reflection by every plane containing axis, we say it is axially symmetric with no swirl, that is to say, is axially symm...
