中文摘要：

文章采用三维建模软件Solidworks对水润滑橡胶艉轴承进行几何建模,并导入ANSYS Workbench中建立有限元模型。通过对水润滑橡胶艉轴承进行十阶模态分析,结果表明轴承的各阶固有频率分布非常密集,其低阶模态主要取决于内衬的固有特性。为了进一步得到轴承在某一频率范围内的振动情况,对其进行了谐响应分析,计算出轴承易发生共振的频率、应力幅值,为水润滑橡胶艉轴承进一步设计优化和使用中避免发生共振提供了理论依据。

英文摘要：

The 3D Modeling Software Solidworks was used to model the water lubricated rubber stern bearing, and the finite element model was established in ANSYS Workbench. Ten modals of the water lubricated rubber stern bearings were analysed. The conclusion shows that the natural frequency distribution at every stage of the bearings is concentrated, and the low modal mainly depends on the inherent characteristics of the lining. In order to obtain the vibration of bearing in a certain frequency range, the harmonic response analysis was carried out, knowing the frequency and stress amplitude of resonance of the bearings, which provids a theoretical basis for the further design optimization and the use of the water lubricated rubber stern bearings.
