Abstract

This paper presents the design of an automatic loading system for mortars equipped with dual coordinating arms and establishes a dynamic model of the coordinating arm automatic loading system. An experimental scheme for a single coordinating arm automatic loading system is designed to verify the accuracy of the simulation results. A comparative study of the dynamic simulations between the dual coordinating arm and single coordinating arm automatic loading systems is conducted, exploring the dynamic characteristics of the dual coordinating arm automatic loading system over different time intervals. The results indicate that the dual coordinating arm significantly mitigates vibrations compared to the single coordinating arm; as the system stiffness increases, the ammunition supply process becomes smoother. The acceleration of the dual coordinating arm exhibits convergence, with longer system lengths resulting in extended loading times. The optimal structural dimensions for the dual coordinating arm are identified, leading to a 34% increase in loading speed compared to the single coordinating arm. This study investigates the dynamic characteristics of the coordinating arm automatic loading system and the impact of structural variations on loading speed, laying the foundation for further structural optimization and precision control.
