ANALYZING RESISTANCE ON PNEUMATIC TIRES USING ENERGY MODEL

Abstract

During movement, wheels’ deformation causes energy dissipation. Viscous
resistance of rubber materials in tire’s carcass and tire’s patterns affect vehicle’s
rolling resistance. This paper analyzes rolling resistance on interaction surface
between tires and road, using energy model based on non-linear Mooney-Rivlin
with two parameters of stress and deformation. The research is on 3-D tire model
in case of static structure, transient structure and explicit dynamics, using finite
element simulation in Ansys Workbench. The results are energy consumption and
rolling resistance of 2 types of flat tires in F1 racing cars and tires with longitudinal
patterns in cars. From here it is possible to analyze further rolling resistance in
other types of tires.
