...Roshan Lal; Rahul Saini In this article, the effect of Pasternak foundation on free axisymmetric vibration of functionally graded circular plates subjected to mechanical in-plane force and a nonlinear temperature distribution (NTD) along the thickness direction has been investigated on the basis...

... of the system are analyzed. According to the various types of wave loads which ship faces on ocean, the influence of the stern structure on the vibration characteristics of the shafting is obtained. It is concluded that the coupling degree of shafting and stern structure is correlated with the natural frequency...

... that, with a high connect stiffness between the ball bearings and the casing; the vibration response on the casing was attenuated very little compared with the response on the bearing house. However, with a low connect stiffness, the attenuation of the vibration response on the casing was great, and the impulse...

...Hakan Yazici; Rahmi Guclu; Ibrahim B. Kucukdemiral; M. N. Alpaslan Parlakci This paper is concerned with the design of a robust, state-feedback, delay-dependent H ∞ controller for an active vibration control of seismic-excited structural systems having actuator delay, norm bounded uncertainties...

...Kari Tammi Resonance vibrations (critical speeds) play a significant role in rotor vibration control. Active vibration control methods for rotors are studied to develop solutions to enhance machines’ dynamic behavior, durability, and operating range. This paper reports rotor vibration attenuation...

...Douglas Ivers; Robert Wilson, Ph.D.; Donald Margolis A classic tuned vibration absorber (TVA) is a device that, when attached to a structure, will greatly reduce the motion of the attachment at a specific excitation frequency. When a fixed frequency input is present, a TVA can be manufactured...

...Henry A. Sodano; Daniel J. Inman There exist many methods of adding damping to a vibrating structure; however, eddy current damping is one of few that can function without ever coming into contact with that structure. This magnetic damping scheme functions due to the eddy currents...
