We all know that tires are a crucial component of the chassis and substantially influence the vehicle dynamics. But how much is \u2018substantially\u2019? And can how can tire modeling solutions contribute to a better overall driving safety and behavior?<\/p>\n

If this triggered your attention, let\u2019s make it yet more compelling \u2026 How about getting all the above, while speeding up your time-to-market, and balance the vehicle\u2019s performance with NVH and aerodynamics? I hear you thinking: \u201cNow, we\u2019re talking!\u201d<\/p>\n

In the Handbuch Kraftfahrzeugtechnik<\/a>, the influence of road, tires and the vehicle for a myriad of attributes such as acoustics, steering, friction is depicted.<\/p>\n

\"Vieweg\u2019sInfluence of road, tires and vehicle on functional performances, as studied in Vieweg\u2019s Handbuch Kraftfahrzeugtechnik<\/span><\/span><\/p>\n

When looking at the graph, you see that for driving behavior and driving safety, the impact of road and tires mounts to approximately 50% of the total vehicle\u2019s performance. Fifty percent! Five zero! I guess you agree that this is quite substantial.<\/p>\n\n\n

A substantial 50%<\/h2>\n\n\n\n

Now we understand how substantial the impact of road and tires is on the overall vehicle dynamics performance, it doesn\u2019t surprise you to know that vehicle OEMs, chassis, and vehicle integration departments are more and more considering the tire as an integral vehicle component. In discussions we have with vehicle OEMs, we experience that manufacturers are more and more cascading stricter requirements to tire manufacturers.<\/p>\n\n\n\n

Additionally, vehicle manufacturers see the essence to have a well-defined and accurate representation of tire behavior throughout the vehicle development process. By doing so, they can virtually validate the performance and robustness of sub-systems, balance performances, and speed up the time-to-market.<\/p>\n\n\n\n

That\u2019s all interesting. But back to the 50% that combines road and tire influences. Obviously, there\u2019s not much we can do about the road surface. The tires and vehicle dynamics performance on the contrary\u2026 here, you enter our domain.<\/p>\n\n\n\n

Tire modeling <\/h2>\n\n\n\n

We recently hosted the webinar: Tire modeling for an outstanding grip on vehicle dynamics<\/a> targeting vehicle OEMs, integration, and chassis departments. Many OEMs and suppliers attended and discovered how standardized tire modeling, ranging from tire testing over model parameterization to model application, helps to accurately simulate tire performance throughout the vehicle design process.<\/p>\n\n\n\n

Illustrated by application examples, our expert Willem Versteden, described modeling techniques with increasing level of detail, from Pacejka\u2019s Magic Formula to Finite Element modeling and Computational Fluid Dynamics. Additionally, Willem described the impact of tire performance on the vehicle\u2019s safety systems performance, aerodynamics, NVH comfort, durability, and hydroplaning.<\/p>\n\n\n\n
