Short Description

« The FTire package provides an interface to the well known FTire tire force model by Prof. Gipser , FH Esslingen, Germany (COSIN). It is especially useful when driving on an uneven road and when tire deformations have to be taken into account.  »

Long Description

«In several Modelica vehicle libraries there are tire force models available directly implemented in Modelica. These tire models comprise some simple models and several versions of PACEJKA's Magic Formula tire. They are suitable for handling simulations on rather even roads. On the other hand there are commercial tire models also accounting for the internal tire dynamics.

The FTire Interface package makes available the FTire model in Modelica models by a set of external functions (which do not have to bother the normal user). An FTire wheel model is simply connected to the wheel carrier parts by the usual MultiBody connector. There are versions to model the tire force calculated for the (rotating) wheel hub and the (non-rotating) wheel carrier.

The road part may be a moving part as well enableing the modeling of test rigs. Road surface and dynamic tire visualization is possible also showing tire deformations during simulation. Special blocks reporting e.g. tire temperature at a particular spot of the tire, or the height at a certain road position are available. There is a complementary package FTireVDL demonstrating the compatibility with Modelon's Vehicle Dynamics package.»
