Title Dynamic analysis and control for automatic ammunition supplying machine of an artillery

Abstract

The chain transmission mechanism is used for the automatic ammunition supplying machine of a self-propelled artillery, the chain (storage cartridge) is driven by the sprocket which is driven by the motor when the automatic ammunition supplying machine works. The three-dimensional solid model and multi-body dynamics model are established in this thesis for the automatic ammunition supplying machine of a self-propelled artillery based on the Lagrange equations of the first kind. The collision of the mechanism and influence of the transition process of the motor on the dynamic parameters are considered in the model. The ADAMS software is used to simulate and solve the dynamic equations of the automatic ammunition supplying machine, and the dynamic response of the mechanism as well as the motion law and the vibration shape in the course of ammunition feeding action are obtained. And finally, analysis and calculation of the results are conducted by using ADAMS and MATLAB/Simulink co-simulation.
