【摘要】：自救脱险是潜艇失事后脱险救生的主要手段，而快速上浮法作为现在最先进、最安全、应用最广泛的自救脱险方式，已在英美等发达国家得到了广泛的应用。 本文根据机械原理、机械设计、材料力学、弹塑性力学理论，采用ANSYS有限元分析、ADAMS虚拟样机技术等研究方法，再结合压力容器的设计准则，对快速上浮脱险装置的脱险筒进行了设计研究，主要包括以下几个部分： （1）根据快速上浮法对快速上浮脱险装置脱险筒的功能要求和技术参数，确定了脱险筒的总体设计方案。并遵循压力容器的设计准则，合理地设计了脱险筒的筒体结构。 （2）在Pro/E软件下建立脱险筒筒体结构的三维模型，并导入ANSYS有限元分析软件中，实现了脱险筒边缘应力的有限元分析，直观的得到了所需的应力和应变分布云图。 （3）设计了脱险筒的上盖开盖机构，并针对该机构中的开式齿轮传动做了理论分析。分析结果修正了开式齿轮传动的几个重要参数，表明当调整齿顶高系数为h*a=0.7，压力角α=150，变位系数x1=0.5，x2=0.5时，开式齿轮传动中轮齿的抗磨损性和抗断齿的能力得到了明显的提高，，齿轮的工作寿命也随之增强，同时还减小了摩擦损失，提高了齿轮传动的效率。 （4）利用Pro/E软件建立了脱险筒上盖开盖机构的三维模型，并导入机械动力学仿真软件ADAMS中，实现了脱险筒开盖过程的动力学仿真。仿真结果分析了开盖过程端盖的运动变化及其影响因素。 最后，总结了一下本文的主要研究工作，并提出了需要进一步研究的工作展望。
[Abstract]:Self-rescue and rescue is the main means of rescue and rescue after submarine crash. As the most advanced, safest and most widely used self-rescue and rescue method, fast floatation has been widely used in the developed countries such as the United States and the United States.

According to the design criterion of pressure vessel, the cylinder structure of escape cylinder is designed reasonably. (2) the 3D model of the escape cylinder structure is established under the Pro/E software, and the finite element analysis software ANSYS is introduced to realize the finite element analysis of the edge stress of the escape cylinder, and the required stress and strain distribution cloud diagram is obtained intuitively. (3) the upper cover mechanism of escape cylinder is designed, and the open gear transmission in the mechanism is analyzed theoretically. Some important parameters of open gear transmission have been corrected by the analysis results. It is shown that when the coefficient of tooth top height is adjusted to be Hau A0.7, the pressure angle 伪 = 150, and the displacement coefficient x 1 0. 5 X 2 = 0. 5, In the open gear transmission, the wear resistance and the ability to break the gear are obviously improved, and the working life of the gear is also enhanced. At the same time, the friction loss is reduced, and the efficiency of the gear transmission is improved. (4) using Pro/E software, the 3D model of the escape cylinder upper cover mechanism is established, and the mechanical dynamics simulation software ADAMS is introduced to realize the dynamic simulation of the escape cylinder open cover process. The simulation results show that the movement of the end cap and its influencing factors are analyzed. Finally, the main research work of this paper is summarized, and the prospect of further research is put forward.
