The main body of recreation wind tunnel is a kind of typical thin shell structure

and the loads added on it are very complex

so some questions must be considered in the design phase

including static strength

static stiffness and dynamics characteristics.Some finite element equations are deduced according to the element analysis and the Hamilton Principle in this paper

and the results of static analysis and model analysis are obtained by analyzing the main body with CAE software-MSC/Nastran and f...
