Dynamic Modeling and Durability Analysis from the Ground Up

Vehicle manufacturers currently use dynamic modeling, finite element modeling, and durability analysis to incorporate reliability into their designs. Although these models are often used separately, there has been little effort toward integrating these analyses and performing an analysis from the "ground up" (i.e., using terrain data to determine dynamic stress and strain). This paper outlines the approach of an ongoing analysis of a US Army trailer, using an integrated process of dynamic modeling, finite element modeling, and durability analysis. This project outlines an approach to mechanical reliability analysis that can be used early in design.
