Introduction to MF-SWIFT/MF-Tyre

Altair HyperWorks now supports the Magic Formula (MF), MF-SWIFT Tire, and MF-Motorcycle Tire developed by TNO. Magic Formula (MF) based tires from TNO are suitable for a wide range of applications, and are primarily used in vehicle handling and stability simulations in conjunction with relatively smooth road surfaces.

•

MF-SWIFT Tire models are suitable for vehicle ride comfort studies, durability, and vibration analysis. With MF-SWIFT it is possible to capture tire dynamic behavior up to 120Hz. The model contains a representation of the tire carcass and sidewalls as a rigid ring with six degrees of freedom. A sophisticated model of contact patch is also included, which is able to simulate effects of partial sliding and tread element compliance. The MF-SWIFT Tire model includes a Magic Formula steady state model, making it suitable also for use in vehicle handling events.

•	MF-Motorcycle Tire models can be used to accurately capture tire dynamics at high level of camber angles (up to 60 degrees).
