The Positioning Accuracy And Experiment Research Of The Cartridge Box Transport System Of The Naval Gun

For a modernized naval gun,the traditional ammunition magazine system that rely on human and semi-automated system is not only time-consuming,and the security and solidity is not high,but has been unable to satisfy the demands of modern naval warfare,so how to design a high speed,stable,reliable,accurate and up ammunition for automatic ammunition magazine system has become an important factor that related to the naval gun’s combat capability,and the problem is also the focus of scholars.This paper propose a new type of cartridge box transport system to study the ammunition magazine system’s shell-feeding system,in which the jacking shells device is the most important module of the cartridge box transport system that is used for realizing the shell’s single launch,and its performance especially the positioning accuracy will directly affect the reliability of the whole system.After studying the structures and principle of modularized ammunition magazine and transport mechanism at home and abroad,the structure scheme of the cartridge box transport system is proposed.The design guidelines and operation principle are introduced Firstly,and designed the mechanical structure of the modules of the system,then finished the design of the system’s control scheme according to the control system’s design requirements,and determined the control mode of the servo systems.For the positioning accuracy problem of jacking shells device,it introduced the composition and control mode of the jacking shells device’s screw feeding servo system,and analyzed the influence of the stiffness,clearance,friction and other factors on positioning accuracy of screw feeding servo system,at the same time it established the screw feed servo system’s integrated model which including these factors to finish simulation analysis by Matlab / Simulink,and at last,the simulation results that the influence of the stiffness,interval,friction,work load’s change,outside interference and other factors on positioning accuracy of screw feeding servo system is got.In order to improve the positioning accuracy of jacking shells device that can ensure the shell launch smoothly,on the basis of studying the screw feeding servo system’s positioning accuracy,through combining the fuzzy control,immune control with PID control,it got thefuzzy immune adaptive PID control,which is used to control the screw feeding servo system’s position loop,and compared the fuzzy immune adaptive PID control’s simulation results with PID control’s simulation results,finally it verified the control mode is feasibility.The prototype of cartridge box transport system is made according to its structure scheme,and designed the hardware and software of the control system by XPC rapid control prototyping technology,,and finally completed the experiments,the experimental results show that the contents of this article is rationality and the system is feasibility.
