Schematic Design And Comprehensive Performance Analysis On Continuous Rotary Feeding Ammunition System

The feeding system is the key part of Warship Weapons. The comprehensive performance of feeding system affects directly combat capability of Warship Weapons. Taking the high-efficiency, speediness and consecutiveness as the main goal, this paper had a research on the mechanism and the way of continuous rotary feeding system, designed and optimized continuous rotary revolving barrel feeding ammunition system which can send the ammunitions 160rpm from single-double sides, analyzed the comprehensive performance of the feeding system under random and symmetric-recycle load spectrum, harmonic wave load,shock loads. Combing with the MOGA in Ansys/Workbench, the paper carried out optimization design to the box of the feeding system. This article had a research on the low efficiency of feeding ammunition, instability of feeding ammunition, the poor vibration resistance system of feeding ammunition and low durability using resonance theory and fatigue analysis theory. By the analysis of optimizing results, enhanced the stability, increased Vibration resistance and improved the service life of feeding ammunition system, thus ensuring the efficiency of feeding ammunition system.First of all, this paper mainly performed a design on the shape of dialing ammunition gear, the shape of cam and motion path of ammunition based on types and principle of feeding ammunition system without chains. The initial solution model of feeding ammunition system was got by the design above.Secondly, dynamic analysis including modal analysis, harmonic analysis and single point response spectrum analysis is carried out to the established model by Ansys/Workbench.By this analysis results, the resonance frequency which shouldn’t appear in the processing of ammunition movement can be avoided and the response performance under the condition of random waves can be confirmed.Again, the paper performed a projection to the fatigue problems of continuous-rotary feeding system without chains combining the above performance analysis to make sure the structure under combating, met the life requirements and obtain a high safety factor so that structure can have a durability and safety in the process of movement. The simulation results proved the practicability, reliability and security of the schematic。Finally, this paper compared the finite element analysis results un-optimized to optimized results. The paper carried out structure optimization to the feeding system based on the results of modal analysis and fatigue life analysis and analyzed the performance of optimized model, Structure Parametric optimization is carried out under meeting the strength and the stiffness to make sure the frame body to achieve a better structure including lighter weight, smaller deformation and more appropriate stressThe method applied in this paper has certain reference value in the research of feeding ammunition system.
