Strength Prediction and Correlation of Tow Hook Systems Using Finite Element Analyses

摘要

In this paper, tow hook systems and their functional objectives are briefly introduced. General analysis considerations in strength prediction of a tow hook system are described. These considerations contain nonlinear, clamping and material property simulations. Connections and loading simulation of a tow hook system model are discussed in detail. A correlation example of a tow hook system is illustrated. This study shows that detailed modelling of a tow hook system is a fundamental requirement for accurate strength prediction and good correlation between finite element analysis and testing.
