Dynamic load identification for stochastic structures based on Gegenbauer polynomial approximation and regularization method
A new approach is considered to identify dynamic loads for stochastic structures. The Gegenbauer polynomial expansion is used to transform stochastic structures. A modified regularization method is adopted to overcome the ill-posedness. The bounds and average coefficients of the identified loads are given.
