โœฆ Synopsis

The dynamic characteristics of a rotating curved beam are investigated. The equations of motion include all dynamic e!ects such as Coriolis force, centrifugal force and acceleration. The analysis of the rotating beam takes into account the coupling between rigid-body motion and elastic deformation, such that geometrically non-linear e!ects are included in the model. For dynamic analysis, the time responses for accelerating motion and torque-driven motion are calculated. The natural frequencies for curved beams of various radii of curvature are then calculated as the rotating speed increases. This study mainly discussed the e!ect of curvature that can change the characteristics of the beam. The e!ects of tip mass on the dynamic response of the beam are also studied.

In this paper, the equations of motion for a deploying beam with a tip mass are derived by using Hamilton's principle. In the dynamic formulations, the beam is divided into two parts. One part of the beam is outside the rigid support and is free to vibrate, while the remaining part is inside the sup

This paper describes an analytical model for a beam system, based on a modiยฎed Timoshenko theory, where the beam is pinned to a hub driven by an actuator at one end and is subject to a heavy load at the other end. A new ecient computational algorithm is then proposed for solving the higher-order non

The deterministic and random vibration response analysis of a model which simulates a robotic arm has been presented. The model is considered as a uniform, mass-loaded, hysteretically damped beam, the left end of which is attached by both translational and rotational springs and the right end of whi
