| Abstract |
To improve the service life of the slewing bearing, the location of the roller subjected to the
maximum load is identified using both finite element analysis (FEA) and experimental methods. The
plastic deformation behavior of solid and hollow rollers under identical operational conditions is subsequently compared. The accuracy of the simulation results is verified through experimental testing,
thereby ensuring the reliability of the analysis. Additionally, simulation data under different degrees of
hollowing are systematically analyzed through curve fitting. The results suggest that the optimal hollowness for minimizing plastic deformation is 18% for the main thrust force and 36% for the reverse
thrust force, with a notable reduction in plastic deformation under these conditions. These findings
indicate that optimizing the hollowing design can effectively reduce plastic deformation. |
