What is FTire?

FTire is the leading high-frequency and short-wavelength tire model for vehicle NVH and ride comfort analysis. FTire is used by engineers in the vehicle and tire industry worldwide. Highly sophisticated 2D and 3D road surface evaluation methods and a powerful toolbox for tire and road data processing make FTire the most comprehensive software package for tire dynamics simulation in the market.

Key Features & Benefits

Benefits
  • Structural dynamics based, full 3D nonlinear in-plane and out-of-plane tire model for simulation of belt dynamics, local pressure distribution in the contact patch, rolling resistance, side-wall contact, large camber angles and misuse scenarios.
  • Suitable for a frequency range up to 200Hz, excited by short surface wavelength, mass imbalance, non-uniformity or irregular tread patterns.
  • Very fast and flexible. Orders of magnitude faster than explicit FE models.
  • Simulation of imbalances by inhomogeneous mass distribution and local wear.
  • Belt temperature distribution model.
  • Support for user-defined wear and temperature distribution models.
  • Full integration of cosin/road digital road library with support for complex rigid time-invariant and time-variant road surfaces.
  • Full integration of cosin/soil digital road library with support for flexible and deformable road surfaces.
  • Advanced online animation with belt deformation animation, pressure distribution plots, road surface visualization and movie export.
  • Robust, multi-core system enabled solver engine.
  • Parameter editing and validation tools included.
  • Tailored parameter fitting tool (FTire/fit) available.
  • Good correlation to measurements.

Applications

FTire is comprehensively used for the following applications:

  • Automotive Engineering
  • NVH Simulation
  • Road load prediction
  • Ride comfort and Driving Dynamics
  • High-Frequency Road Excitation
  • Non-Linear Tire Dynamics

Modules

  • FTire/core
  • FTire/tools
  • cosin/3Droad
  • cosin/2Droad
  • cosin/3Droad
  • cosinGL
cosinGL is an external executable that can be automatically launched by MotionSolve in conjunction with FTire simulations. It allows users to visualize the animation of the tire and road and display various tire states at run-time. cosinGL Overview and User Guide

*All cosin products are available on Linux (reference platform is RHEL4+5, others will work anyway), Windows XP, Windows Vista, Windows 7 and Mac OSX. For all platforms 32 and 64-bit versions are available.
