Dynamic Modeling of Helicopter Aerogun System Based on Transfer Matrix Method

Abstract

The aerogun system is an indispensable automatic shooting weapon on the armed helicopter. The system is a complex mechanical system with large motion and small deformation, in which multiple rigid bodies and flexible bodies are connected in a certain way. In this study, the system dynamics model of the armed helicopter aerogun was established by using the multi-body system transfer matrix method. The finite element model for dynamic analysis of helicopter aerial gun is established, and the modal calculation and dynamic response analysis of key connection parts are carried out. t lays a foundation for adjusting the vibration frequency by changing the state parameters. So as to reduce vibration and improve shooting accuracy.
