轨道炮动力学特性仿真分析

摘要

Based on the general dynamic model of railgun, with the focus on the expression of the dynamic response of rail, conduct the sensitivity analysis of the influence factors of critical speed, seek the maximum influence factors of critical speed of the rail gun, provide the support for the structural design of the rail gun. With the regard to the launch device of cer-tain rail gun, use the software of Ansys to conduct the numerical simulation of aerodynamics, and compare the simulation analysis with the result of theoretical calculation methods, provide the reference accordance for the further research on the characteristics of the rail gun and the optimization design for the railgun.%基于电磁轨道炮通用动力学模型,围绕轨道动态响应表达式,对临界速度影响因素进行敏感度分析,寻求轨道炮的临界速度最大影响因子,为轨道炮的结构设计提供支撑.针对某轨道炮发射装置,利用有限元软件Ansys进行动力学仿真计算,并对仿真分析与理论计算结果进行对比,为进一步研究轨道炮特性及身管优化设计提供参考依据.
