【摘要】：自救脫險是潛艇失事后脫險救生的主要手段，而快速上浮法作為現(xiàn)在最先進(jìn)、最安全、應(yīng)用最廣泛的自救脫險方式，已在英美等發(fā)達(dá)國家得到了廣泛的應(yīng)用。 本文根據(jù)機(jī)械原理、機(jī)械設(shè)計、材料力學(xué)、彈塑性力學(xué)理論，采用ANSYS有限元分析、ADAMS虛擬樣機(jī)技術(shù)等研究方法，再結(jié)合壓力容器的設(shè)計準(zhǔn)則，對快速上浮脫險裝置的脫險筒進(jìn)行了設(shè)計研究，主要包括以下幾個部分： （1）根據(jù)快速上浮法對快速上浮脫險裝置脫險筒的功能要求和技術(shù)參數(shù)，確定了脫險筒的總體設(shè)計方案。并遵循壓力容器的設(shè)計準(zhǔn)則，合理地設(shè)計了脫險筒的筒體結(jié)構(gòu)。 （2）在Pro/E軟件下建立脫險筒筒體結(jié)構(gòu)的三維模型，并導(dǎo)入ANSYS有限元分析軟件中，實現(xiàn)了脫險筒邊緣應(yīng)力的有限元分析，直觀的得到了所需的應(yīng)力和應(yīng)變分布云圖。 （3）設(shè)計了脫險筒的上蓋開蓋機(jī)構(gòu)，并針對該機(jī)構(gòu)中的開式齒輪傳動做了理論分析。分析結(jié)果修正了開式齒輪傳動的幾個重要參數(shù)，表明當(dāng)調(diào)整齒頂高系數(shù)為h*a=0.7，壓力角α=150，變位系數(shù)x1=0.5，x2=0.5時，開式齒輪傳動中輪齒的抗磨損性和抗斷齒的能力得到了明顯的提高，，齒輪的工作壽命也隨之增強(qiáng)，同時還減小了摩擦損失，提高了齒輪傳動的效率。 （4）利用Pro/E軟件建立了脫險筒上蓋開蓋機(jī)構(gòu)的三維模型，并導(dǎo)入機(jī)械動力學(xué)仿真軟件ADAMS中，實現(xiàn)了脫險筒開蓋過程的動力學(xué)仿真。仿真結(jié)果分析了開蓋過程端蓋的運(yùn)動變化及其影響因素。 最后，總結(jié)了一下本文的主要研究工作，并提出了需要進(jìn)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 theory of mechanical principle, mechanical design, material mechanics, elastoplastic mechanics, ANSYS finite element analysis and ADAMS virtual prototyping, and combined with the design criteria of pressure vessel, The design and research of the escape cylinder of the quick floating escape device are carried out, which mainly include the following parts: (1) according to the functional requirements and technical parameters of the rapid floating escape device, The overall design scheme of escape cylinder is determined. 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 偽 = 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.
