Improving Fatigue Life for Truck Axles-A Specimen Case of Using NASA Technology 780073
This paper describes a method for determining the effect of proposed geometric, material property, or manufacturing process changes on component fatigue life. The method integrates the application of field load data acquisition, analytical stress analyses, cyclic material properties, and strain based fatigue concepts. Fatigue life is then used as a major design change acceptability criterion. One of the key steps in this qualification process is the use of NASTRAN, a finite element stress analysis program developed by NASA.
