Nonlinear resonance of trapped waves on a plane beach
… of the nonlinear mechanism of sub-harmonic resonance. This type of theory has been extended by Minzoni & Whitham (1977), Rockliff (1978), and Rockliff & Smith (1985), among others. Rockliff also initiated a. theory whereby subharmonic resonance can be achieved by an incident wave of …

Modeling, Simulation, and Analysis of Micromechanical Filters Coupled with Capacitive Transducers
… for the response of the filter to a primary resonance. The third objective is to investigate the feasibility of employing subharmonic excitation to build bandpass filters consisting of either two sets of two beams coupled mechanically or two sets of clamped-clamped beams. Throughout this …

Forced, nonlinear, planar and nonplanar oscillations of a cantilvered beam including static deflection
… considered whirling produced by a primary resonance. In this dissertation, secondary resonances are considered in addition to primary resonance. Previous derivations of equations of motion contain only the linear and cubic terms without consideration of the static displacement produced by …

Nonlinear vibration of beam and multibeam systems
… configuration was a subcombination internal resonance. However, for the same beam in the vertical configuration, both a subcombination internal resonance and a nonresonant modal interaction were observed to transfer energy to a low-frequency mode. The subcombination internal resonance …

A Theoretical and Experimental Study of Nonlinear Dynamics of Buckled Beams
… of external harmonic excitations and internal resonances. We assume that the beam geometry is uniform and its material is homogeneous. We initially buckle the beam by an axial force beyond the critical load of the first buckling mode, and then we apply a transverse harmonic excitation that is …

Nonlinear dynamics of composite plates and other physical systems
… solutions in the neighborhoods of different resonances. As an application of the technique, the nonlinear response of a fluid-relief valve is discussed in detail. The different resonances are studied, and in each case the responses are compared to those obtained by using the Galerkin …

Modeling and Simulation of Microelectromechanical Systems in Multi-Physics Fields
… their fundamental natural frequencies (primary-resonance excitation). We investigate the dynamic pull-in instability and formulate safety criteria for the design of MEMS sensors and RF filters. We also utilize this phenomenon to design a low-voltage RF MEMS switch actuated with a combined DC and …

Applications of almost periodic functions and equivalent nonlinearities to identification and control of nonlinear systems
… The system is also shown to exhibit subharmonic resonance apci jump phenomena. In chapter 6 the use of dither in adaptive control systems is discussed, and the specific case of dither adaptive control system proposed as the solution to a qonstant fuel-rate problem is analysed in …
