Research on Air-Structure Coupling Dynamic Characteristics of Sounding Board Driven by Gunpowder Pulsation

Abstract:

In this paper the author tries to establish the corresponding air-structure coupling dynamic characteristic equation of the sounding board system, in line with the coupling fluid flow as well as the prestress conditions, then this dynamic characteristic equation is simplified.The coupling modal of the whole sounding board system is calculated by using the software of ansys, and the data of gunpowder explosion pressure pulsation is obtained from the calculation in autodyn, then the frequency and modal of the sounding board system were further analyzed in the software of ansys. The results show that there are some significant changes in the frequency and modal of the sounding board system under the condition of prestress as well as the air-structure coupling of gunpowder pulsation fluid flow.
