A Novel Running-in specification with Strengthening Effects in Fatigue

Using two types of automobile transmission assemblies, a novel running-in specification with strengthening effects is proposed and investigated by the strengthening of lowamplitude forces below the fatigue limit. The phenomenon is also referred to as understressing or coaxing. In this novel running-in specification, the fatigue life will be prolonged and the assembly cost is unchanged. The average fatigue life of one transmission assembly was increased ~40 % when the original running-in force was replaced by the optimal strengthening force in the new running-in specification. The average fatigue life of the other type of transmission assembly was improved ~26 % when the estimated optimal strengthening force was applied in another new running-in specification with the strengthening effects.
