Abstract

The ammunition coordinator is an important part of automatic ammunition loading system of a large caliber artillery. It is a complex electromechanical system,and its performance will directly affect the accuracy,reliability and safety of automatic ammunition loading system. In order to analyze the factors affecting the dynamic characteristics of the ammunition coordinator and improve the reliability of the coordination in place,the simulation and experimental study of the system were carried out. The ammunition dynamics model and control system model of the coordinator were established by using Adams and Simulink software respectively. The electromechanical joint simulation model of ammunition coordinator was established based on interactive interface. The motion characteristic of the mechanical and electrical system was analyzed. The measured angle of coordination process was compared with the simulation results. The comparison results show that,the co-simulation model can accurately describe the motion characteristics of the ammunition coordinator. On this basis,two representative failure modes during actual debugging such as the spline wear,local damage of bearing,were selected. The fault simulation analysis were carried out using fault injection technique. The effect of the spline wear and local damage of bearing on the movement process of system was determined. The fault simulation results show that,the greater the spline wear degree and the bearing friction coefficient,the unstabler the motion coordination is. The fault injection method based on co-simulation can provide a reference for the analysis of factors affecting the reliability of coordination in place,and the analysis results can provide a basis for the fault analysis of the system.
