It turns out that SIMULIA’s FEA simulation software is used by nearly every tire manufacturer in the world to simulate realistic tire performance such as inflation, rolling resistance, noise, tire-road contact, hydroplaning and even behavior of the tire during anti-lock braking! One of SIMULIA’s customers, Hankook Tire Co. Ltd, even presented their work on tire traction in snow at a SIMULIA Community Conference.

One of the major challenges of this type of work is the fact that snow is a tricky material; it doesn’t behave like your everyday engineering materials, so the first step is to develop the right material model to capture the extreme deformation and break-up of the snow. The tire also requires an advanced material model to model the tire deformation as you drive. The guys at SIMULIA created a complete multiphysics model of a tire, wheel and braking system and the impact of snow on its behavior. The results of this type of this work is shown below and they are very impressive. The team modeled both the snow movement and break-up as well as the tire deformation as the car braked (enlarge the below GIF to see how the tire reacts to the snow).
SIMULIA has both the power and sophistication to handle this type of complex analysis allowing tire manufacturers, and indeed other companies, to understand product performance without requiring physical prototypes.
So while you wait for warmer weather to come our way, check out this awesome clip about simulating the tire-snow interaction including anti-lock braking systems!
