Quarter model with tire (Magic Formula) SimScape Driveline

Hello,

I want to use Tire (Magic Formula) block to simulate behavior of quarter of car. What should I do with H port? H port shoul provide longtidual force.

Best regards

Hello Marcin,

The H port is a translational conserving port associated with the hub of the tire. It should be associated with the longitudinal motion of the vehicle. You can see in sdl_vehicle_4wd that the H ports are connected to the Vehicle Body. This can also be done with a half or quarter car model.

Is it possible to add additional weight (e.g. cargo) to the Vehicle Body?

Can I use Vehicle body to simulate 3D motion?

[Martin]

If the additional mass is constant throughout the simulation, you can treat the vehicle and cargo together, and enter the parameters as if they are one unit.

If you would like the additional cargo to change or move separately from teh vehicle during simulation, there is an option starting in R2019a to have physical signal inputs to account for this.

The Simscape Driveline block can handle longitudinal translational and pitch. For full 3D motion, use Simscape Multibody.
