Operational Modal Analysis of Wind Turbine Speed- increase Gearbox
Speed increase transmission gear box is the primary vibration and noise source of wind turbine, Operational modal method was adopted to collect impact data and response data of each point based on the gearbox test model. ANSYS finite element model is established to simulate the wind turbine gearbox. Then the modal frequencies of the two methods were compared to ensure the test model is correct....
متن کاملNonlinear Dynamic Simulation of Coupled Lateral-torsional Vibrations of a Gear Transmission System
Nonlinear dynamic model of the coupled lateral-torsional vibrations of a gear transmission system is developed, in which time-varying gear meshing stiffness, errors, and gaps are considered. The fundamental rules of the system’s multi-harmonic dynamic response have been obtained based on the time domain diagram, frequency domain diagram, phase plot, and Poincaré map. Therefore, estimation of th...
متن کاملMulti-body Dynamics and Modal Analysis of Compliant Gear Bodies
This paper extends the multi-body dynamics modelling strategy for rigid gears to include compliant gear bodies in multi-mesh transmissions. Only external, fixed center, helical or spur gears are considered. This formulation combines distributed gear mesh stiffness and gear blank compliance models in a multi-body dynamics framework resulting in a set of non-linear differential equations with tim...
متن کاملVibration analysis of coupled double-nanocomposite microplate-systems
The aim of the paper is to analyze electro-thermo nonlinear vibration of a double-piezoelectric composite microplate-system (DPCMPS) based on nonlocal piezoelasticity theory. The two microplates are assumed to be connected by an enclosing elastic medium which is simulated by Pasternak foundation. Both of smart composite microplates are made of poly-vinylidene fluoride (PVDF) reinforced by zigza...
متن کاملModal analysis of vocal fold vibrations using laryngotopography
In this paper, we propose a method for analyzing spatial characteristics of the larynx during phonation by high-speed digital imaging. The laryngotopography was applied to the high-speed digital images of normal subjects, and patients with paralysis and cyst. The results show various modes of vibration of the vocal folds particular to the patients with paralysis and cyst and usefulness of the l...
