中文摘要
复杂海洋环境等因素作用下水下发射平台的运动随机性显著,严重干扰航行体出水运动及均压排气过程,影响发射成败。本课题拟在随机平台运动带来的新特征基础上,以考虑平台运动的带排气航行体出水仿真结果为样本,基于非嵌入式混沌多项式展开法进行带排气航行体出水不确定量化研究。揭示平台运动不确定性伴随航行体出水的传播规律,明确航行体排气参数及运动参数对各随机条件的敏感性,探究均压排气改善随机平台运动下航行体出水稳健性的作用机制及效果。特色与创新在于:①基于减压罐排气实验及开放水箱弹射实验构建真实的航行体出水仿真方法;②采用蒙特卡洛法准确标定不确定性量化方法,并基于全真实流场仿真结果构造样本空间。在还原平台运动随机本质的基础上实现带排气航行体出水不确定性量化,弥补水下发射在可靠性数据及研究方法的空白,为未来开展高性能、高可靠性潜射系统设计奠定基础。
英文摘要
Under the influence of the complex marine environment and other factors, the motion of underwater launch platforms shows significant stochastic characteristics, which seriously interferes the water-exit motion and the pressure-equalizing exhaust process of the vehicle, affecting the launch success. Based on the new features brought by the stochastic platform motion, this subject will use the simulation results of the water-exit vehicle with exhaust considering the platform motion as samples, and carry out the uncertainty quantification on the water-exit process of the vehicle with exhaust based on the Non-Intrusive Polynomial Chaos Expansion method. This subject will reveal the propagation law of the uncertainties in the platform motion accompanied by the water-exit process of the vehicle, clarify the sensitivity of the exhaust parameters and the motion parameters of the vehicle to the stochastic conditions, and explore the mechanism and effect of pressure-equalizing exhaust on improving the robustness of the water-exit process of the vehicle under the stochastic platform motion. Features and innovations are as follows: ① constructing a real simulation method for the water-exit process of the vehicle based on the decompression tank exhaust experiment and the open tank ejection experiment; ② using the Monte Carlo method to accurately calibrate the uncertainty quantification method, and constructing the sample space based on the results of the full real flow field simulation. This subject will realize the uncertainty quantification of the water-exit vehicle with exhaust on the basis of restoring the stochastic nature of the platform motion. These results will fill the gaps in reliability data and research methods for underwater launch, and lay the foundation for the future design of high-performance, high-reliability underwater launch systems.
