Liquid Propellant Gun Filling System Simulation Studies

Liquid ProPellant (LP) can effectively improve the performance and characteristic of conventional artillery in the army, so it is important and practical to resrearch the liquid propellant inject system for realizing project application of the LPG. The inject system must achieve automatic precision inject and flexible variable charge.The main works of this thesis is focused on the following aspects:1)According to the technical characteristics target of a certain type Artillery,the design performance standard of inject system is achieved.2)Compared with a variety of inject ways which previously studied, the inject plan in accordance with the requirements of this system has determined,the relevant structural design has completed. In order to chieve accurate inject,the Permanent magnet linear synchronous motor(PMLSM) is selected on the displacement precision control of the inject cylinder's piston. the control mode and form of this inject system has been researched too.3)Based on the software of MATLAB/Simulink and AMESim,take the inject system which has been designed as the object,carry on the modeling and co-simulation analysis.Verify the rationality of model through the analysis result,study the dynamic characteristic of inject system when some structural parameters has changed.Through the analysis of the co-simulation results,the LP inject system can satisfy the performance requirements of LPG,it is fessible in theory and can achieve rapid,accurate inject and flexibly change. Although the results have yet to validated by experiments,some aspects still exist deficiencies,but the dominant thinking of the design,modeling and simulation mechods and the analysis results still has certain reference value for related research in future.
