摘要: A new experimental identification technique of a two-dimensional vibrating elastic structure with geometrical nonlinearity is considered. First it shown that the governing equations given in form nonlinear partial differential can always be transformed to those ordinary called modal equations, and hence reduced determination equations. Then for determining parameters through use data proposed. Numerical simulation conducted typical cases, applicability confirmed.
