Mathematical models for determination of the residual stresses on gears

Abstract

This paper deals with the influence of residual stresses on the total value of loading and describes a method for measuring and calculating residual stresses and the total value of loading in the example of a gear. Since experimental methods are slow and expensive and are almost impossible to be carried out in the phase of product designing, on the basis of experiments and years of experience, various semi-numerical methods to determine residual stresses have been developed. The significance of the suggested methods is that in the calculations residual stresses can be taken into account even if there is no relevant experimental data. Thus the accuracy can be increased as, for example, in determining the life span of project products.
