Cosin scientific software delivers software for diverse and accurate tire simulation. With, FTire (Flexible Structure Tire Model), vehicle and tire manufacturers, suppliers, engineering companies, research institutes and universities worldwide can build tire simulation models for high-frequency and short-wave-length excitation. It finds various applications in several tire dynamics phenomena and is available in key MBS, multi-physics system, and FEA simulation environments.

It is also useful for primary and secondary ride comfort simulation, NVH, and prediction of road loads on road irregularities. Given that it is a highly nonlinear and dynamic tire model, it is used extensively to study flat or bumpy roads, especially in the case of demanding suspension control systems design.

FTire Product Suite

The FTire suite of products includes FTire/core, which is a 3D flexible structure virtual tire that comes with dedicated solver extensions. In addition, FTire/fit is a standalone product for parameter identification out of measurements. FTire/sim consists of a fast and efficient tire dynamics and road-related simulation toolkit.

Users also benefit from powerful cosin/tools that are capable of handling FTire data and cosin Road Data DRM. This allows for digital rights management and road data encryption.

FTire is unique since it enables the prediction of complex tire phenomena on a strictly mechanical and thermo-dynamical basis, and produces reliable results as compared to purely mathematical curve approximation.

It also offers online monitoring, result analysis, and reporting capabilities as well as advanced pre- and post-processing features, in addition to powerful model parameterization tools and scripted simulation prospects.
