摘 要: Bearings are a vital part of rotating machinery, it's very important to understand the parameters affecting its performance and to find its Remaining Useful Life (RUL). To predict the RUL of a defected bearing, we have used a hybrid model. Combining the physics-based models with data-based model i.e., tuning the parameters of the physics-based equations with data from Finite Element Simulations, then interpolating for the remaining values gives us a broad look over the correlation between the parameters. In this paper, we have used a modified rating life equation, L_(nmr), as given in ISO 16281. The model is robust, we have tried to consider every parameter that can affect RUL as a variable. Results are graphically represented for a better understanding of how the RUL is getting affected with the change in range of parameters.

轴承是旋转机械中的关键部件,了解影响其性能的参数并确定其剩余使用寿命(RUL)至关重要。为了预测故障轴承的剩余使用寿命,我们采用了一种混合模型。该模型结合了基于物理的模型与基于数据的模型,即通过有限元仿真数据对物理方程的参数进行调优,再进行插值以获取剩余寿命的数值,从而全面分析各参数之间的关联性。本文采用了ISO 16281中给出的修正后的额定寿命公式L_(nmr)。该模型具有良好的鲁棒性,我们尽可能将所有可能影响RUL的参数作为变量纳入考虑。结果以图形方式呈现,以便更清晰地理解参数范围变化对RUL的影响程度。
