Aim The kinematics analysis is processed to the ammunition supplying mechanism in the autoloader system of a self propelled gun.Methods Based on the model simplification of the ammunition supplying mechanism

with the theory about robot kinematics and dynamics

the kinematic equation is established. Results The moving locus is programmed. The general analyzing software about the kinematics is worked out. The locus of each rigid body in the ammunition supplying mechanism is provied. And the new kinematic research about the ammunition supplying mechanism is analyzed. Conclusion The results prove that the ammuition supplying mechanism moves steady and smoothly with good controlling performarce. The design project is reasonable.
