Two models for the parametric forcing of a nonlinear oscillator
Parametric excitation Resonance Chaos Elliptic averaging
2015/8/27
Instabilities associated with 2:1 and 4:1 res-onances of two models for the parametric forcing of a strictly nonlinear oscillator are analyzed. The first model involves a nonlinear Mathieu equation an...
Slow Passage through Multiple Parametric Resonance Tongues
Parametric excitation slow passage multiple resonances amplification
2015/8/27
This work concerns linear parametrically excited systems that involve multiple resonances. The property of such systems is that if the parameters are fixed and lie inside a resonance tongue, the motio...
Parametric Excitation and Evolutionary Dynamics
Parametric Excitation Evolutionary Dynamics
2015/8/27
Parametric excitation refers to dynamics problems in which the forcing function enters into the governing differential equation as a variable coefficient. Evolutionary dynamics refers to a mathematica...
A Parametric Study on the Starting Transients of a Vacuum Ejector-Diffuser System
Parametric Starting Transients Vacuum Ejector-Diffuser System Fluid Dynamics
2012/4/24
In this endeavor, the transients persisting in a vacuum ejector system (put reference of my old paper) is studied by numerically simulating the flow field, and experimentally validating the simulated ...
Parametric study on supersonic flutter of angle-ply laminated plates using shear deformable finite element method
Panel flutter Angle-ply laminates Fiber orientation Flow yaw angle Length-to-thickness ratio
2012/2/29
The influence of fiber orientation, flow yaw angle and length-to-thickness ratio on flutter characteristics of angle-ply laminated plates in supersonic flow is studied by finite element approach. The ...
