In the single-point mooring (SPM) system, the main bearing is a critical component that withstands mooring force, making its load-bearing performance under actual working conditions of great significance. However, research on this type of bearing remains limited, and existing studies have not considered the actual mooring force and installation structure. Therefore, this study focuses on the Soft Yoke Mooring System (SYMS) and proposes an overall finite element equivalent modeling method for the main bearing, by considering the mooring force and installation structure. In addition, to avoid extensive nonlinear contact problems, rollers and bolts are equivalently modeled using nonlinear springs and beam elements. After verifying the model's accuracy, we compare it with the traditional model under equivalent load and analyze the effects of upper load, bolt preload, and friction coefficient on the load-bearing performance of the main bearing. Finally, based on the maximum roller load obtained from both the overall and traditional models, a local contact model is established to calculate the safety factor of the main bearing. The results indicate that the overall equivalent model more accurately reflects the load distribution and deformation characteristics of the main bearing. Both the overall displacement and the bolt displacement decrease with increasing preload and friction coefficient, while contact pressure exhibits an increasing trend. The calculated safety factor of the main bearing in the overall model is 1.43, which is significantly lower than the safety factor of 2.51 obtained from the traditional model. This indicates that the traditional model overestimates the load-bearing capacity of the main bearing, while the overall model provides a more accurate assessment. Thus, the overall model provides a more reliable basis for the design of such bearings.

单点系泊系统中,主轴承作为承受系泊力的关键部件,其在实际工况下的承载性能研究具有重要意义。但目前针对该类轴承的研究较少,现有研究也未考虑到其实际系泊受力形式和安装结构的影响。为此,本文以软刚臂式单点系泊系统为研究对象,提出了考虑系泊受力以及安装结构的单点系泊主轴承整体有限元等效建模方法,为了避免大量的非线性接触,该方法利用非线性弹簧和梁单元对滚动体及螺栓进行等效处理。在验证整体模型准确性后,将其与载荷等效后的传统模型进行对比,并分析了上部载荷、螺栓预紧力以及摩擦系数对主轴承承载性能的影响。最后,基于整体与传统模型所得到的滚子最大载荷,建立了局部接触模型,进而计算主轴承安全系数。结果表明:整体等效模型更能准确反映主轴承的受力与变形特性;整体模型的位移及螺栓位移随着预紧力以及摩擦系数增大而减小,而接触压力呈增大趋势;计算得到整体模型下的主轴承安全系数为1.43,明显小于传统模型所得安全系数2.51,由此可见,传统模型会高估主轴承的承载能力,而整体模型能对主轴承的承载能力进行准确评估,从而为该类轴承的设计提供更为准确的依据。
