CAE Analysis of Heavy Duty Truck CAB Bridge and Method of Comparing CAE Results and Vehicle Test Data to Find the Most Important Loading Condition 2016-28-0242

This paper reinforces the importance of correlation between CAE Analysis of CAB Bridge and Vehicle test data. CAB Bridge is a structural assembly, bolted to the Frame of a Truck. The initial objective of the study was to evaluate the influence of particular design modification on CAB Bridge. To perform CAE calculations, two different iterations of Boundary & loading conditions, were established and executed using CATIA V5. During Post processing of CAE results, detailed data analysis and interpretation were performed. The results of CAE Analysis and Vehicle test data were compared, to identify the iteration that correlated better with Vehicle test data. The data analysis and interpretation guided in finding key observations and concluding that the Torsion case as the most important loading condition.
