chrono::vehicle::ChVehicleCosimDBPRigImposedAngVel Class Reference
Description
Drawbar-pull rig mechanism with imposed angular velocity.
This mechanism enforces a prescribed wheel angular velocity. A linearly increasing resistive force is applied against the forward motion of the vehicle and the experiment is ended when the vehicle stops. At each time, the vehicle forward speed and resulting slip are calculated and stored together with the current resistive force (DBP). This experiment produces the entire slip-DBP curve at once.

◆ SetRampingIntervals()
| void chrono::vehicle::ChVehicleCosimDBPRigImposedAngVel::SetRampingIntervals | ( | double | delay, |
| double | ramp_time | ||
| ) |
Set the delay and ramping time intervals for reaching the prescribed angular velocity.
By default, the angular velocity is kept zero for 0.2 s and then increased to the prescribed value in 0.5 s.
