Finite Element Analysis to Ceramic Ball Pure Rolling Contact Stresses

摘要：

　　The RCF (Rolling Contact Fatigue) life of bearing balls is a main method,to evaluate the performance of bearing materials and their production technology.In general,The RCF life of ceramic balls is a reliable technique to asses whether or not they are suitable to be used in rolling bearings.The RCF life of ceramic balls is depend on contact stresses chiefly.It applies the finite element analysis to calculate the surface stresses and subsurface stresses,including 1st principal tensile stresses and shear stresses.The theory results are compared with the finite element solutions.Very good agreement is observed.The finite element results in this paper have an important applied value.The results provided theoretical basis for rolling contact fatigue life prediction of the ceramic balls.
