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.
期刊介绍：
Mechanics of Solids publishes articles in the general areas of dynamics of particles and rigid bodies and the mechanics of deformable solids. The journal has a goal of being a comprehensive record of up-to-the-minute research results. The journal coverage is vibration of discrete and continuous systems; stability and optimization of mechanical systems; automatic control theory; dynamics of multiple body systems; elasticity, viscoelasticity and plasticity; mechanics of composite materials; theory of structures and structural stability; wave propagation and impact of solids; fracture mechanics; micromechanics of solids; mechanics of granular and geological materials; structure-fluid interaction; mechanical behavior of materials; gyroscopes and navigation systems; and nanomechanics. Most of the articles in the journal are theoretical and analytical. They present a blend of basic mechanics theory with analysis of contemporary technological problems.
