Abstract

To investigate the effect of various factors on bearing stress response, Huber-Hencky-von Mises stress serves as a bridge, the equivalent interrelation between radial loading, axial loading, and temperature of bearing is studied using finite element method (FEM). Symbolic regression (SR) algorithm is employed to analyze simulation results, establishing a functional expression between independent and dependent variables by optimizing combinations of variables, constants, and functional forms. The results showed that within the specified force and temperature values, the curved surface of the equivalent correlation function, trained using the SR algorithm, demonstrates smoothness. Both training and validation data exhibit a strong correlation with this curved surface. Among the three factors, temperature exerts the greatest influence on bearing stress values, followed by radial loading, and axial loading components had the smallest impact.

轴承工作载荷评估等效方法
为了研究各种因素对轴承应力响应的影响,以 Huber-Hencky-von Mises 应力为桥梁,使用有限元法(FEM)研究了轴承径向载荷、轴向载荷和温度之间的等效相互关系。采用符号回归(SR)算法分析模拟结果,通过优化变量、常数和函数形式的组合,建立自变量和因变量之间的函数表达式。结果表明,在指定的力值和温度值范围内,使用 SR 算法训练的等效相关函数的曲面表现出平滑性。训练数据和验证数据都与该曲面表现出很强的相关性。在三个因素中,温度对轴承应力值的影响最大,其次是径向载荷,而轴向载荷对轴承应力值的影响最小。
