摘要
火箭弹垂直发射转弯过程是非线性动力学过程,为解决巨型规模的最优弹道解算问题,研究了分布式并行计算方法,建立了最优弹道的并行求解模型,研制了专用仿真软件。仿真分析结果表明:在满足一定的参数精度要求的情况下,最优控制弹道问题具有极好的并行性,分布式并行计算可显著提高计算效率,问题的求解时间随并行机节点数的增加而成比例的缩短。
The swerve of the vertical launch of rocket ammunition is a non-linear dynamic process. To solve the giant- scale optimum problem, the distributing parallel computation is researched, the parallel solving model of the optimum trajectory is established and the special simulation software is developed. The simulation analytical results demonstrate that distributing parallel computation can increase significantly the computing efficiency with the definite precision range of the parameters because the controlling trajectory has the extreme parallelism. The computing time is proportionally shortened with the increase of the node number of the parallel machine.
