At the 2018 nCode User Group Meeting, Accuride presented an introduction of fatigue analysis in the commercial truck wheel industry followed by an implementation of nCode DesignLife used for calculation of Required Fatigue Strength (RFS). Predicting fatigue damage and RFS are two methods for evaluating biaxial load testing of wheel subject to prescribed loading profiles. One of the next steps identified in the presentation was the need for follow up correlation work.
This presentation is a continuation that summarizes the correlation of measured time series biaxial test data with predicted analytical values using nCode GlyphWorks and DesignLife. The correlation begins with evaluating control input loading versus actual wheel force reactions. A strain gaged wheel is used to measure wheel strains that can be used to compare single cycle strain histories as well as test fatigue damage and RFS values. Comparisons are made with predicted values using DesignLife.
This correlation project identified area for improvement in our testing and data analysis processes. Improvements opportunities in FEA loading are also pointed out. Next steps will be to update our correlation process followed by repeated testing and failure mode correlation.
