Double-layer cylindrical shell vibration response simulation method and device

The invention provides a double-layer cylindrical shell vibration response simulation method and device, and belongs to the field of mechanical engineering.The method comprises the steps that the function relation of a double-layer cylindrical shell vibration displacement response model is determined; according to dimensional analysis, converting the parameters to obtain a scaling relational expression of which the dependent variable is the ratio of the vibration displacement response to the shell length and the independent variable is dimensionless; according to the scaling relational expression, obtaining a conversion relation between each control parameter of the double-layer cylindrical shell and a corresponding control parameter of the scaling model based on a similarity law; according to the actual control parameters and the conversion relation of the double-layer cylindrical shell, control parameters of the scaling model are obtained for vibration response simulation, and based on ...
