AI Technical Summary
Existing technologies make it difficult to accurately predict the cage whirl velocity deviation ratio during the bearing design stage, resulting in long R&D cycles, high costs, and difficulty in proactive design.
A nonlinear model framework and response surface methodology are adopted. A calculation model for the eddy velocity deviation ratio is constructed using the hyperbolic tangent function and a complete quadratic polynomial. The model weight coefficients are trained through orthogonal experiments and the least squares method to achieve rapid prediction of the eddy velocity deviation ratio.
It enables rapid and accurate prediction during the bearing design phase, shortens the R&D cycle, reduces costs, provides a theoretical basis for parameter optimization, and improves the operational reliability and design efficiency of bearings.
