FTire Product Suite

The Tire Simulation Software Suite FTire consists of its main product FTire/core, the 3D flexible structure virtual tire with dedicated solver extensions, the standalone product FTire/fit for parameter identification out of measurements and FTire/sim a fast and efficient tire dynamics and road-related simulation toolkit.

In addition users are provided with the powerful cosin/tools to handle FTire data and cosin Road Data DRM enabling digital rights management and road data encryption.

Key features

Detailed fully nonlinear 3D tire structure deformation model covering all frequencies up to 250 Hz and higher
Brush-type dynamic tread-road contact model with a resolution below 1 mm. Optional use of geometrical tread patterns is supported
Tire imperfection models including tread gauge variation, imbalance effects, conicity and non-uniformity
Optional misuse contact elements like rim-to-belt (bottoming), sidewall-to-road, and rim-to-road
Solver extensions for tread wear, bulk and tread surface temperature, air volume vibration, flexible rim, and deformable road
cosin’s digital road models supporting rigid, flexible, time-invariant or time-variant road surfaces, and 3rd-party user-written road descriptions, e.g. OpenCRG, RDF, etc.
Comprehensive tools for parameter editing, validation as well as statics, steady-state, modal, and linearization analyzes
Online animation of detailed belt deformation, pressure distribution, and road surface attributes
Interface to arbitrary user-defined FE-based rim flexibility models
Interface to user-defined soft-soil and flexible road surface models
Multi-core system enabled solver
Solver extension for realtime execution on selected platforms
Comprehensive parameter identification tool

What is unique?

FTire predicts complex tire phenomena on a strictly mechanical and thermo-dynamical basis. It provides much more reliable results than any purely mathematical curve approximation ever can.
FTire features powerful model parameterization tools and scripted simulation prospects. In addition it comes with online monitoring, result analysis, and reporting capabilities as well as advanced pre- and post-processing features.
Re-use of the same high-quality tire models throughout the entire tool chain and the whole development process, from the office, over HiL to the testbed systems across all departments.
Even a full featured FTire structural dynamics model can run under hard realtime conditions.
