Parametrically Excited Helicopter Ground Resonance Dynamics With High Blade Asymmetries
The present work is aimed at verifying the influence of high asymmetries in the variation of in-plane lead-lag stiffness of one blade on the ground resonance phenomenon in helicopters. The periodical equations of motions are analyzed by using Floquet’s Theory (FM) and the boundaries of instabilities predicted. The stability chart obtained as a function of asymmetry parameters and rotor speed re...
متن کاملDynamics of a nonlinear parametrically excited partial differential equation.
We investigate a parametrically excited nonlinear Mathieu equation with damping and limited spatial dependence, using both perturbation theory and numerical integration. The perturbation results predict that, for parameters which lie near the 2:1 resonance tongue of instability corresponding to a single mode of shape cos nx, the resonant mode achieves a stable periodic motion, while all the oth...
متن کاملGlobal Dynamics of a Parametrically and Externally Excited Thin Plate
Both the local and global bifurcations of a parametrically and externally excited simply supported rectangular thin plate are analyzed. The formulas of the thin plate are derived from the von Kármán equation and Galerkin’s method. The method of multiple scales is used to find the averaged equations. The numerical simulation of local bifurcation is given. The theory of normal form, based on the ...
متن کاملLocal Dynamics of Defects in Parametrically excited Waves
We present an experimental study on the local dynamics of parametrically excited waves at an air–water interface when defects are present in the wave pattern. The probability density function (PDF) of the local wave amplitude displays an exponential part for values close to the average amplitude and decreases sharply to zero for large amplitudes. The power spectral density (PSD) of the local am...
متن کاملElectrochemically-actuated Morphing Helicopter Blade
The use of the expansion of lithium-ion cells for mechanical actuation has been recently reported by Chin et. al. (1). Under a stress of 10 MPa, actuating strains of up to 1.5% were achieved. Taking into account the cells approximate elastic modulus, this strain corresponds to a mechanical energy density ten times higher than that of current piezoelectric materials, although with slower actuati...
