为了寻找导弹发射系统最佳的设计参数,提高发射精度,提出了一种基于虚拟样机技术和遗传算法联合仿真的多参数优化方法。首先建立了发射系统的动力学模型,根据工程实际设计了优化参数,然后利用ADAMS与MATLAB建立了导弹发射系统的联合仿真模型,最后运用遗传算法编制了优化程序并进行优化计算。优化结果表明,导弹滑离时的初始扰动得到降低,提高了发射精度,证明该联合仿真的优化分析方法是可行的。

In order to find optimal design parameter of launching system and improve launching precision, a multi-parameter optimization algorithm based on virtual prototype technology and genetic arithmetic was proposed. First, dynamic model of the missile system was estab- lished. The optimal parameters were designed according to engineering practice. Then,the co-simulation model of ADAMS and MATLAB was established. Finally, the code of optimization was programmed based on the genetic algorithm and the simulation was conducted. The results show the initial disturbance of missile decrease and the launching accuracy is improved. It is proved that the multi-parameter optimi- zation algorithm is feasible.
