| 摘 要： | 本文构造运载火箭姿态运动的并行数字仿真模型。首先将姿态运动的隐式数学模型变换到显式模型,然后应用预处理数值积分方法离散化,并将其计算量均匀地分配给各个处理机,最后构造了各个处理机之间的同步方法。实际计算表明,本文构造的并行仿真模型的计算复杂性小,具有较高的加速比。

| Abstract: | In this paper, the parallel digital simulation model of the attitude motion of a launch vehicle is constructed. Firstly, the implicit mathematical model of the attitude motion is transformed into the explicit model. Secondly. the preprocessed numerical integration method is applied to the explicit model in order to obtain the discretization, and workload per step is distributed evenly among the processors of the multiprocessor system. Finally. the synchronization mechanism of the executions of different processors is constructed. The practical computation demonstrates that there are smaller complexity and higher parallelism in the parallel simulation model constructed in this paper. |
