摘 要： Calculation with the determined load is more useful for engineering applications because the external load is easier to obtain than the bearing eccentricity. However, the calculation method based on the determined load for a journal bearing with a complex structure is still difficult to meet requirement. This article presents a calculation method to seek proper bearing eccentricity with a determined external load according to response surface methodology. The relationship between the relative eccentricity and attitude angle of the journal bearing and the external load is determined according to response surface optimization. The Navier-Stokes and elastic deformation equations are adopted during calculation of lubricating properties. The validity of the calculation method is verified with the experimental results. Moreover, the method is proved to be applicable to calculation of the fixed load based on the Reynolds equation.

采用已确定的载荷进行计算在工程应用中更为实用，因为外部载荷比轴承偏心距更容易获得。然而，对于结构复杂的滚动轴承，基于已确定载荷的计算方法仍难以满足要求。本文提出一种基于响应面法的计算方法，用于在给定外部载荷下求解合适的轴承偏心距。通过响应面优化方法，确定了滚动轴承相对偏心距与倾角以及外部载荷之间的关系。在润滑性能计算过程中，采用了纳维-斯托克斯方程和弹性变形方程。该计算方法的可靠性已通过实验结果得到验证。此外，该方法还被证明适用于基于雷诺方程计算固定载荷的情况。
