An elegant and accurate method for determining the number of clamped-clamped natural frequencies of a bending-torsion coupled beam which lie below a specified frequency is presented. The method facilitates an easy and straightforward application of the Wittrick-Williams algorithm when finding natural ...
The equation of motion is derived by using a generic joint in the middle of clamped-clamped beam. A behavior of natural frequency sensitivities is studied as a function of nondimensional linear and torsional spring stiffnesses.关键词: Joint stiffness Lap joint Natural frequency sensitivity Lumped ...
It corresponds to the variation of resonance frequency due to a change in its mass [22]:R=∂f∂m=−12f0mwhere f0 and m are the SNR resonance frequency and mass, respectively. In order to maximize the mass responsivity, a beam should thus have both high resonance frequency and small...
They used a magnetic field at an extremely low temperature (4.2 K) to excite a clamped–clamped microbeam using two AC signals of a frequency that were extremely close to each other and to the fundamental natural frequency of the beam. They determined that by exceeding a certain threshold of...
Micromanipulation and biological, material science, and medical applications often require to control or measure the forces asserted on small objects. Here, we demonstrate for the first time the microprinting of a novel fiber-tip-polymer clamped-beam pro
The axial displacements are approximated with the first vibration mode clamped-camped beam functions. The ordinary trigonometric series are employed to represent the displacements in hoop direction. The buckling problem is reduced to the calculation of the minimum eigenvalue for the homogeneous system of...

Theoretical modeling and analysis of a novel frequency up-converted energy harvester based on clamped-clamped beamHarvesting ambient vibration to replace the traditional battery power supply strategy and offer energy for electronic devices has drawn the attention of numerous researchers. However, the ...
In order to support this claim, a cantilever beam with the same material and geometrical characteristics with the plain harvester (Wb and Lb) is designed and excited in its first natural frequency (224.4 Hz). For a similar loading (body load of 0.0011 N) the maximum displacement of ...
