چکیده

A thorough understanding of the effects sloshing on aircraft dynamic loads is great relevance for future design flexible to be able reduce their structural mass and environmental impact. Indeed, high vertical accelerations caused by vibrations structure can lead fragmentation fuel free surface. Fluid impacts tank ceiling are potentially a new source damping that has hardly been considered before when computing wings. This work aims at applying recently developed reduced-order models case research wing investigate aeroelastic response under pre-critical post-critical conditions. The dynamics using neural networks trained with experimental data from scaled then integrated into system following suitable scaling procedure. results concern gust input (flutter) conditions as well highlighting onset limit cycle oscillations sloshing, only nonlinear phenomenon modelled in present simulation framework. Moreover, load alleviation performances will assessed typical landing input.

Support-Vector-Machine-Based Reduced-Order Model for Limit Cycle Oscillation Prediction of Nonlinear Aeroelastic System

It is not easy for the system identification-based reduced-order model ROM and even eigenmode based reduced-order model to predict the limit cycle oscillation generated by the nonlinear unsteady aerodynamics. Most of these traditional ROMs are sensitive to the flow parameter variation. In order to deal with this problem, a support vector machineSVMbased ROM was investigated and the general cons...

mortality forecasting based on lee-carter model

over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...

Parametric reduced order model approach for simulation and optimization of aeroelastic systems with structural nonlinearities

A method based on Parametric Reduced Order Models to efficiently predict the transient response of aeroelastic systems with concentrated structural nonlinearities is presented. The approach approximates the nonlinear response in a piecewise-linear manner through time integration of sub-linear reduced order models; these are parameterized with respect to the nonlinearity and are efficiently obta...

Novel Radial Basis Function Neural Networks based on Probabilistic Evolutionary and Gaussian Mixture Model for Satellites Optimum Selection

In this study, two novel learning algorithms have been applied on Radial Basis Function Neural Network (RBFNN) to approximate the functions with high non-linear order. The Probabilistic Evolutionary (PE) and Gaussian Mixture Model (GMM) techniques are proposed to significantly minimize the error functions. The main idea is concerning the various strategies to optimize the procedure of Gradient ...
