In this study, a semi analytical method for transverse and axial vibration of single-walled boron nitride nanotube (SWBNNT) under moving a nanoparticle is presented. The surrounding elastic medium as Pasternak foundation and surface stress effect are included in the formulations of the proposed model. Using Timoshenko beam theory (TBT), Hamilton’s principle and nonlocal piezoelasticity theory, ...

The present study is the first to analyze the dynamic response of a poroelastic beam subjected to a moving force. Moreover, the influences of attached mass-spring systems and non-ideal supports (with local movements in the supporting points or base due to the presence of factors such as gaps, unbalanced masses, and friction or seismic excitations) on the responses were investigated. Non-ideal s...

Semi-mechanized and mechanized harvesting use machines that promote the transference of vibrational energy impact to achieve detachment coffee fruits. The aim this study was evaluate vibration transmissibility in fruit-peduncle systems, using high-speed cameras, submitted high frequency harmonic excitation different combinations between amplitude vibration, identifying working ranges suitable p...

in the current study, the effects of interactions of the moving loads and the attached mass-spring-damper systems of the composite plates on the resulting dynamic responses are investigated comprehensively, for the first time, using the classical plate theory. the solution of the coupled governing system of equations is accomplished through tracing the spatial variations using a navier-type sol...

This paper aims at assessing the effect of dry friction on dynamic behaviour a damped mechanical system subject to harmonic forcing. Previous work systems highlighted that not including other forms damping in analysis can lead unrealistic results such as presence infinite resonances. In this contribution, an exact solution is derived for continuous steady-state response multi-degree-of-freedom ...
