【摘要】 本文主要完成了潜射弹道运载器分离体下沉过程砸艇概率的研究。为了摸清分离体在分离时刻的初始运动学参数可能的变化范围，首先计算了导弹运载器的水下弹道。而后根据初始运动学参数，计算了运载器分离体的下沉弹道，并且分别讨论了分离体的总体参数、流体动力学参数和初始运动学参数对下沉弹道的影响。同时根据正交试验的思想，分析了不同的初始运动学参数对于下沉弹道的影响程度，并且给出了这些因素的主次顺序。然后利用蒙特卡罗法和复合形方法相结合的优化方法进行了分离体初始运动学参数的优化设计，同时对分离体下沉弹道的各项指标进行了优化计算。定量的确定了分离体下沉的极限范围。在对分离体下沉的各种干扰因素进行了深入的分析后，建立了基于蒙特卡罗方法的潜射导弹运载器分离体砸艇概率的计算模型，并且进行了大量的计算机仿真试验，分别对运载器采用平面弹道，偏航弹道在不同发射深度，不同发射艇速的情况下的分离体砸艇概率进行了仿真计算，给出了不同情况的砸艇概率。并对仿真结果进行了分析，为工程上解决运载器分离体的砸艇问题提供了一定的理论依据。更多还原

【Abstract】 This paper studies the probability of smashing the submarine when the segregator of the submarine launched missile carrier sinking in the water. In order to investigate the variety of some of the initiatory kinematics parameters, the author first computes the underwater trajectory of the submarine launched missile carrier. Later the author computes the underwater trajectory of the segregator of the submarine launched missile carrier, then discusses the influence to the underwater trajectory from the hydrodynamics parameters, collectivity parameters and the initiatory kinematics parameters. At the same time the author used the means of statistics to find out the various degrees of influence from the different initiatory kinematics parameters and gives the primary and secondary order. Then the author optimize the initiatory kinematics parameters of the segregator of the submarine launched missile carrier by the way of Monte Carlo and simplex. Confirming the limit scope of the segregator of the submarine launched missile carrier when sinking. Then in this paper the author establishes the simulation model of the probability of smashing the submarine when the segregator of the submarine launched missile carrier sinking in the water and uses the Monte Carlo (Of or relating to a problem-solving technique that uses random samples and other statistical methods for finding solutions to mathematical or physical problems.) to simulate the whole process. Then the author carrier through much simulating computations and gives the smashing probability at different conditions. So this paper gives some help to the engineering practice.更多还原
