Dynamic Analysis of Patterned Tire Rolling over Cleat

摘要

Transient dynamic response of rolling tire impacting with a small cleat is analyzed by an explicit finite element method. A 3-D tire model considering detailed tread blocks is used to accurately simulate the local tire-cleat impact process. The frictional dynamic contact problem is formulated by making use of the explicit finite element method and the penalty method. By imposing mass-proportional damping only to the tire parts showing significant lateral deformation, the dynamic viscosity effect is artificially reflected. The vertical/horizontal force histories and resonant frequency responses are numerically predicted and assessed through the comparison with experimental results.
