The free vibration characteristics of isotropic coupled conical-cylindrical shells based on the precise integration transfer matrix method

open access: yesCurved and Layered Structures, 2017
Based on the transfer matrix theory and precise integration method, the precise integration transfer matrix method (PITMM) is implemented to investigate the free vibration characteristics of isotropic coupled conicalcylindrical shells.

Coupled vibrations of a meniscus and liquid films [PDF]

open access: yesJournal of Fluid Mechanics, 2015
We investigate the vibration properties of a circular horizontal film that is bounded by a meniscus (or Plateau border) and suspended between two catenary films. The suspending films act as capillary springs, and the system is thus free to oscillate around its equilibrium position. We study its free and forced oscillations. In our experiments, we track

Vibration Isolation of a Surveillance System Equipped in a Drone with Mode Decoupling

open access: yesApplied Sciences, 2021
Vibration isolation with mode decoupling plays a crucial role in the design of an intelligent robotic system. Specifically, a coupled multi-degree-of-freedom (multi-DOF) model accurately predicts responses of system dynamics; hence, it is useful for ...

The particle-vibration coupling form factor [PDF]

open access: yesPhysics Letters B, 1980
A simple model for calculating the particle-vibration form factor is studied. Explicit expressions of the latter quantity are worked out for various kinds of vibrations, assuming a static, zero range effective interaction. Numerical results for (T=0) and (T =1) octupole vibrations, for Fermi and Gamow-Teller vibrations are given.
