METHODS OF ANALYSIS AND DETERMINATION AND WARPING VALUES OF CRANKSHAFTS

A method for calculating the total warping of crankshafts after vibro-impact treatment is proposed, based on the consideration of residual compression stresses that occur in the surface layers. An analytical model and the results of numerical modeling of warping are presented. A comparative analysis of the results of numerical modeling with the results of calculated data is conducted, which showed their agreement with a relative error of less than 5 %.
