Dynamic Analysis of a Timoshenko Beam Subjected to an Accelerating Mass Using Spectral Element Method

open access: yesShock and Vibration, 2014
This paper presents formulations for a Timoshenko beam subjected to an accelerating mass using spectral element method in time domain (TSEM). Vertical displacement and bending rotation of the beam were interpolated by Lagrange polynomials supported on ...

Implementation of Timoshenko element local deflection for vertical track modelling

open access: yes, 2019
A vertical track model suitable for the study of the dynamic response and the interaction between wheel and rail in the time domain is developed by using Timoshenko beam elements, and its performance is optimised by accounting for the local deflection of

Nonlinear boundary stabilization for Timoshenko beam system

open access: yesJournal of Mathematical Analysis and Applications, 2015
This paper is concerned with the existence and decay of solutions of the following Timoshenko system: $$ \left\|\begin{array}{cc} u"-μ(t)Δu+α_1 \displaystyle\sum_{i=1}^{n}\frac{\partial v}{\partial x_{i}}=0,\, \in Ω\times (0, \infty),\\ v"-Δv-α_2 \displaystyle\sum_{i=1}^{n}\frac{\partial u}{\partial x_{i}}=0, \, \in Ω\times (0, \infty), \end{array ...

Sensing linear viscoelastic constitutive parameters with a Timoshenko beam on a multi-layer foundation: Modeling and simulation

open access: yesSensing and Bio-Sensing Research, 2015
We present a sensor model comprised of a Timoshenko beam coupled with a linear viscoelastic substrate via a distributed system of compliant elements. The system of governing equations includes the evolution of the kinematic descriptors of the Timoshenko ...

Asymptotic limits and stabilization for the 1D nonlinear Mindlin-Timoshenko system [PDF]

open access: yes, 2010
This paper shows how the so called von Kármán model can be obtained as a singular limit of a modified Mindlin-Timoshenko system when the modulus of elasticity in shear k tends to infinity, provided a regularizing term through a fourth order dispersive ...

Continuum Mechanics Modeling of Flexible Spring Joints in Surgical Robots

open access: yesAdvanced Robotics Research, EarlyView.
A new mechanical model of a tendon‐actuated helical extension spring joint in surgical robots is built using Cosserat rod theory. The model can implicitly handle the unknown contacts between adjacent coils and numerically predict spring shapes from straight to significantly bent under actuation forces.

Stabilization of coupled nonuniform Timoshenko beam system

open access: yes, 2005
In this paper, we consider the stabilization problem of a coupled nonuniform Timoshenko beam system using feedback control. It is shown that with linear boundary force and moment feedback controls simultaneously applied at the hinged junction and at one ...

Controller design and stability analysis of Timoshenko beam with input delay

open access: yesJournal of Hebei University of Science and Technology, 2018
In order to study the influence of input time delay on the stability of Timoshenko beam system and stabilize the Timoshenko beam system with input delay and load, by using the Backstepping method, a new controller is designed to compensate for the input ...

Vibration characteristics of axially loaded tapered Timoshenko beams made of functionally graded materials by the power series method [PDF]

open access: yesNumerical Methods in Civil Engineering, 2017
:In the present article, a semi-analytical technique to investigate free bending vibration behavior of axially functionally graded non-prismatic Timoshenko beam subjected to a point force at both ends is developed based on the power series expansions ...
