Computing the Fatigue Strength and Field Life of Shovel Loader Axle Shafts Using Finite Elements 790854
Design analysis of earth moving equipment has been used extensively in recent years. This increased utilization has focused on finite element analysis methods.
This paper presents a method for accumulating, analysing, and interpreting data for effectively meeting design strength analysis needs. This method is used in an example involving a shovel loader axle, as shown in Figures 1 and 2. It indicates how field recorded data is processed by the “rainflow” accumulation method and compared to the strength of the component to determine the calculated field fatigue life. Internal stresses at weld interfaces and the stress concentration at notches are presented.
