A theoretical calculation model for ship stern bearings with large hull deformation is established and validated theoretically and experimentally. A hull simulation model is established to calculate hull deformations corresponding to the reaction force of stern bearings under multi-factor and multi-operating conditions. The results show that in the condition of wave load, hull deformation shows randomness; the aft stern tube bearing load obeys the Gaussian distribution and its value increases significantly compared with the load under static, and the probability of aft stern tube bearing load greater than 1 is 65.7%. The influence laws and levels between hull deformation and bearing reaction force are revealed, and suggestions for ship stern bearing specifications are proffered accordingly.

建立了船体变形较大的船尾轴承理论计算模型，并进行了理论和实验验证。建立了船体仿真模型，以计算在多因素和多工况下与船尾轴承反作用力相对应的船体变形。结果表明，在波浪载荷条件下，船体变形表现出随机性。尾管承受的载荷服从高斯分布，其值与静态载荷相比明显增加，尾管承受的载荷大于1的概率为65.7％。揭示了船体变形与轴承反作用力之间的影响规律和水平，并提出了有关船尾轴承规格的建议。
