CDTire
CDTire offers a family of tire models with different levels of detail and performance characteristics to match various simulation requirements.
Model Comparison
| Model | Use Case | Real-Time | Frequency Range | HIL/SIL/MIL |
|---|---|---|---|---|
| CDTire/3D | Physical, structural MBS tire model – for all applications. | No | Full | No |
| CDTire/Realtime | Hard real-time capable tire model – derived from CDTire/3D – for application on driving simulators and model, software or hardware in the loop. | Yes | Up to 150 Hz | Yes |
| CDTire/MF++ | Magic formula (PAC 2002) extended with temperature effects | Yes | — | Yes |
| CDTire/Thermal | Temperature prediction, can be coupled with CDTire/3D, CDTire/RT and CDTire/MF++ | Yes | Depending on the coupled model | Yes |
Applications
CDTire supports a wide range of vehicle development scenarios:
Durability analysis to predict spindle forces while driving on a durability test track
NVH analysis using transient simulation in time domain or simulations in frequency domain based on linearized models
Tire coupled test rig applications with up to all 6 directions driven for each tire
