Description
Einfluss der Probengröße und der Festwalzparameter auf die Schwingfestigkeit bauteilähnlicher Proben
FKM 1994
Booklet No. 185
Project No. 167
Abstract:
The research project was concerned with the experimental and theoretical analysis and optimization of the deep rolling finishing process, which serves to increase the fatigue strength of metallic components. Approximately 900 round samples of 42 CrMo 4 heat-treatable steel, GGG.60 nodular graphite cast iron and 38 MnVS 5 AFP steel with diameters ranging from 8 to 64 mm were deep rolled in very different ways and vibration tested under rotating bending in order to determine the influence of the process parameters on fatigue strength. In addition to the deep rolling force as the most important parameter, the angle of attack of the rolling roll, the positioning of the rolling roll in the notch and the clearance angle between the rolling roll and the notch also have a significant influence. Optimized deep rolling increased the fatigue strength of 16 mm notch samples by up to 220 %. The fatigue strength of optimized deep-rolled notch specimens decreases more with increasing part size than that of unstrengthened specimens with the same qualitative asymptotic dependence. All experimental results are available on a personal computer in the FRISCO information system developed in-house. The non-linear finite element method was used to simulate the deep rolling of a heel notch for the first time in order to calculate the residual stress field in the notch base, which is particularly important for the fatigue behavior of deep rolled parts.
