Transverse Vibration of an Axially Accelerating String [PDF]

Journal of Sound and Vibration, 1994
Abstract The transverse vibration of an axially accelerating string is investigated. The equation of motion is developed using Hamilton's principle. The resulting partial differential equations are discretized using Galerkin's method. Assuming the axial velocity to be periodic, a stability analysis is performed using Floquet theory. One-, two-, three-

Wormholes, killing horizons and naked singularities: light surfaces in axially symmetric spacetimes

European Physical Journal C: Particles and Fields, 2022
We study several classes of exterior and interior axially symmetric spacetimes, such as wormholes, accelerating black holes, and binary black hole systems, from the point of view of light surfaces related to the generators of Killing horizons.

Transverse vibrations of elevator chain excited by borders motion

Scientific Reports
The paper contains an analysis of transverse vibrations of an elevator chain excited by the movement of the chain ends. The equation of motion of the system was derived using a model of a moving string taking into account the tension force component ...

Transverse vibration of an axially accelerating string

, 2020
ÖZET Eksen doğrultusunda ivmelenen ipin enine titreşimleri incelenmiştir. Hareket denklemi Hamilton prensibinden çıkarılmıştır. Ortaya çıkan kısmi diferansiyel denklem Galerkin metodu ile adi diferansiyel denklemlere dönüştürülmüştür. Galerkin yaklaşımında bir terim alındığında çözümü çok iyi bili nen Mathieu denklemi ortaya çıkmaktadır, iki terim ...
