Member Function Documentation
◆ getTierodBushingData()
|
inlineoverridevirtual |
Return stiffness and damping data for the tierod bushings.
Used only if tierod bodies are defined (see UseTierodBody). Returning nullptr (default) results in using kinematic joints (spherical + universal).
Reimplemented from chrono::vehicle::ChHendricksonPRIMAXX.
◆ UseTierodBodies()
|
inlineoverridevirtual |
Indicate whether or not tirod bodies are modelled (default: false).
If false, tierods are modelled using distance constraints. If true, rigid tierod bodies are created (in which case a derived class must provide the mass and inertia) and connected either with kinematic joints or bushings (depending on whether or not bushing data is defined).
Reimplemented from chrono::vehicle::ChHendricksonPRIMAXX.
