Vibration Analysis of Multilink Manipulators Based on Timoshenko Beam Theory [PDF]

Journal of Robotics, 2011
Timoshenko's theory is adopted in order to accurately describe the freely vibrating dynamics of a multilink flexible manipulator. It is herein presented an analytical modelling strategy that extends previous works through a more refined model which accounts for elastic complicating effects along with lumped inertial loads which are typically mounted on

The Shear Effect of Large-Diameter Piles under Different Lateral Loading Levels: The Transfer Matrix Method

Buildings
In various analytical models, modeling the behavior of large-diameter monopiles and piles can be challenging due to these foundations with huge body sizes carrying mechanisms of lateral loads to the surrounding soils.

On triply coupled vibrations of axially loaded thin-walled composite beams [PDF]

, 2009
Free vibration of axially loaded thin-walled composite beams with arbitrary lay-ups is presented. This model is based on the classical lamination theory, and accounts for all the structural coupling coming from material anisotropy.

Optimal Cantilever Dynamic Vibration Absorbers by Timoshenko Beam Theory [PDF]

Shock and Vibration, 2004
A double‐ended cantilever beam as a distributed parameter dynamic vibration absorber has been applied to a single‐degree‐of‐freedom system subjected to harmonic forces.In this investigation, the beam has been analyzed under the well known model of Timoshenko and the computation of best parameters is based on the Chebyshev’s optimality criterion.This is

The Influence of Mass on Dynamic Response of Cracked Timoshenko Beam with Restrained End Conditions: The Truncated Theory

Applied Mechanics
In this paper, the dynamic response of the Timoshenko cracked beam subjected to a mass is investigated. In turn, it is assumed that the beam has its ends restrained with both transverse and rotational elastic springs. Based on an alternative beam theory,

A Numerical Case Study on Contact Analysis with Large Displacement

MATEC Web of Conferences, 2016
In case of geometrically non-linear analysis of plane frame structures, Bernoulli-Euler beam elements considering the shear deformation to be zero are generally used.

Exponential stability of a class of boundary control systems [PDF]

, 2009
We study a class of partial differential equations (with variable coefficients) on a one dimensional spatial domain with control and observation at the boundary. For this class of systems we provide simple tools to check exponential stability.
