Static aeroelastic analysis including geometric nonlinearities based on reduced order model

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...

Physics-based Sound Synthesis of Stringed Instruments Including Geometric Nonlinearities

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...

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...

Static Aeroelastic Analysis for Generic Configuration Wing

STATIC aeroelastic analysis capability that calculates A flexible air loads for generic configuration wings was developed. It was made possible by integrating a finite element structural analysis code (MSWNASTRAN) and a panel code of aerodynamic analysis based on linear potential flow theory. The framework already built in MSC/NASTRAN was used, and the aerodynamic influence coefficient matrix w...
