The invention relates to a design method for an observation window of a full-sea-depth manned submersible. The method comprises the following steps: carrying out size calculation according to a first observation window parameter and a preset observation window size formula to obtain an observation window target size; carrying out stress calculation according to the first observation window parameter, the observation window target size, the second observation window parameter and a preset stress formula, obtaining the theoretical stress of the observation window, and checking the design of the observation window target size; and performing numerical calculation according to the numerical calculation model, the third observation window parameters and a preset calculation scheme to obtain stress and displacement numerical calculation results of the observation window, and checking the observation window. The observation window checked by the application generally can pass the hydrostatic external pressure test, but in order to ensure the safety of the observation window, the hydrostatic external pressure test is suggested to be carried out to check that the displacement of the observation window does not exceed an allowable value and check that the observation window does not have stress damage. By adopting the method, the problem of accurate design of the core component of the full-sea-depth manned submersible is solved.
本申请涉及一种全海深载人潜水器观察窗设计方法。所述方法包括:根据第一观察窗参数和预设观察窗尺寸公式进行尺寸计算,获得观察窗目标尺寸;根据第一观察窗参数、观察窗目标尺寸、第二观察窗参数和预设应力公式进行受力计算,获得观察窗理论应力并校核观察窗目标尺寸设计;根据数值计算模型、第三观察窗参数和预设计算方案进行数值计算,获得观察窗应力和位移数值计算结果,并对观察窗进行校核。本申请通过上述校核的观察窗,一般均能通过静水外压试验,但为确保观察窗的安全性,建议开展静水外压试验,以校核观察窗位移不超过允许值,校核观察窗不出现应力性损伤。采用本方法,解决了全海深载人潜水器核心部件的精确设计难题。
