摘要:

Aero-thermal-elastic characteristics of hypersonic nonlinear laminated panels considering the shock wave (SW) as well as the aerodynamic heating are studied in this paper. The linear and third order piston theories are used to evaluate the aerodynamic pressure. Hamilton's principle is employed to establish the aeroelastic model of the laminated panel. In the aerothermal model, the heat flux in the aerodynamic heating is computed using the reference temperature method, and the finite element method (FEM) is applied to solve the transient heat transfer in the panel. After solving the aeroelastic and aerothermal models separately, the solutions are substituted into each other. Then performing the procedure of iteration, the coupling effects among the structure, fluid and thermal are realized. Time domain responses of the laminated panel are obtained. The influences of the shock wave on the aeroleastic characteristics of the panel are also investigated. From the numerical simulation, it can be observed that the aeroelastic stability is weakened with the increase of the temperature change. It is also noted that in the calculation of the airflow parameters for the aerothermoelastic analysis in the hypersonic flow, the influences of the shock wave should be taken into account.
