Study of Isight-based Monte Carlo Simulation Technologies for Missile

为提高导弹蒙特卡洛仿真的效率与可靠性,减轻设计人员开发负担,建立了基于Isight的导弹蒙特卡洛仿真环境,实现了弹道参数模块、气动分析模块与弹道仿真模型在环境中的无缝集成,并采用Isight提供的蒙特卡洛工具完成导弹打靶仿真试验。基于上述环境,在考虑发射角误差与随机阵风因素条件下,对某型反坦克导弹六自由度弹道进行蒙特卡洛打靶仿真。结果表明,基于Isight的导弹蒙特卡洛仿真环境能够实现仿真模块快速设置、仿真流程自动化运行以及仿真结果智能化分析,极大降低了设计人员的工作强度,从而验证了有效性和实用性。

To improve the effectiveness and reliability of missile Monte Carlo simulation and release the burden of designers,an Isight-based Monte Carlo simulation environment for missile is established. The missile parameters module,subsystem models as well as other modules are integrated in the environment.The missile Monte Carlo simulation is conducted by the Monte Carlo tool provided by Isight. Based on Isight environment,a six degree of freedom trajectory for certain anti-tank missile is simulated considering random wind interference and initial launch angle deviation. The results shows that the Isight-based Monte Carlo simulation environment for missile can achieve some merits like convenient simulation modules modification,simulation process automatic execution and simulation results analysis,which significantly release the burden of designers. The results illustrate the effectiveness and practicality.
