Modeling and Analysis of a Cantilever Beam Tip Mass System
We model the nonlinear dynamics of a cantilever beam with tip mass system subjected to different excitation and exploit the nonlinear behavior to perform sensitivity analysis and propose a parameter identification scheme for nonlinear piezoelectric coefficients. First, the distributed parameter …

Methodology for nonlinear quantification of a cantilever beam with local nonlinearities
… of (a) certain parameter(s). An Euler-Bernoulli cantilever beam with two nonlinear configurations is used to develop and validate the methodology. One configuration consists of a cantilever beam with a cubic spring attached at a specific distance from the beam root to achieve a smooth nonlinear …

Redesign of FlexLab cantilever beam for reduced resonance frequencies and increased damping
… of efforts to redesign the FlexLab portion's cantilever beam to meet two design goals. First of all, that the frequency of the second natural mode of the beam fall below 100 Hz. Second, that the beam's damping is increased such that the first peak gain is within an order of magnitude of the …

Vibrational Control of a Cantilever Beam Using Sensor and Actuator Averaging Methods
In this paper, governing equations for cantilever beams are derived. We go over sensor and actuator averaging, a method to create a spatial filter that is insensitive to model parameter uncertainty. We develop a controller to actively control cantilever beam vibration using accelerometer input. The …

Transient vibrations of a cantilever beam rotating at a constant angular acceleration
… of a constant angular acceleration to a cantilever beam initially at rest was determined. This method is applicable to beams of uniform cross-sectional area vibrating in their planes of rotation. The governing differential equations include the effects of bending, shear deformation and …

Vibration of a cantilever beam that slides axially in a rigid frictionless hole
… following firing. This research considers a cantilever beam which can move axially in and out of a rigid frictionless hole and is free to vibrate laterally outside the hole. Two Euler equations describing the lateral and axial motion of the beam are presented. A transformation of coordinates …

Both papers employ the cantilever beam approach in which the spur gear tooth is represented as a rigidly supported, cantilever beam of uniform thickness tapered in the plane of load application. Deflection is considered to be caused by bending moment, shearing force, and …
