Researches On Adding Ammunition Technology For Automatic Artillery

Ammunition device is a kind of transmission equipment connected to the ammunition chest, between the car and artillery, its role is to transmit ammunition to entrances of ammunition chest smoothly and quickly, thus improve the ammunition speed, To ensure continuous operational capability of the artillery.In this paper, traditional mode of transportation has been studied, combined with the characteristics of the chain of30, We carried out on the ammunition system function analysis and the corresponding concrete structure design,to determine the technical requirements of the system,conditions,targets and principles of design, Established the transfer scheme with the synchronous belt transmission for rigid guide and the chain slot module for the flexible channel. According to the design principle of optimal solution, to determine the transmission line,power transmission,the structure of the parts.Established a three-dimensional model of each component by using UG software, and explaned the special structure of the modeling process in detail, Especially has carried on a mathematical modeling and theoretical analysis for the flexible guiding part.Established a virtual prototype of ammunition system by using the Recurdyn software,The physical properties of rigid guidance and flexible guidance themselves were simulated.And then respectively analyzed the motion characteristics and dynamic performance of chain transmission in rigid guidance system, the flexible guidance and pluck system. Simulated the process of removing bullet chain,verified the feasibility of removing the bullet chain literally,In the process of removing bullet chain,Using Ansys to generate cbd neutral file and carry out a rigid flexible hybrid simulation with FFlex,analyzed the work of the system of removing bullet chain and the finite element strength of pluck wheel of removing bullet chain mechanism.Based on the rigid body dynamics and finite element simulation of adding ammunition system,research and analysis of mechanics and physical properties of the adding ammunition system from theory and virtual experiment,the simulation results show that, the system structure of this method is feasible,and can provide certain reference and reference to research and application.
