Hi,
we are using simscape multibody for simulating a bicycle and its stability. Our problem is to get the connection between the wheels and the ground so that the bicycle moves foreward owing to the rotation of the wheels.
Thank you very much for any kind of help!
Kind regards
Lennart

Hello,
May I know how you build the bicycle model in simulink? this sure be big help. Thanks in advanced :)

Hi Lennart and Florian, the modeling of contact forces can not be modeled with the normal blocks in the Simscape Multibody library. However Steve Miller (from the MathWorks) has created a library, which solves this restriction: https://de.mathworks.com/matlabcentral/fileexchange/47417-simscape-multibody-contact-forces-library Please have a look at the example "Friction_04_Disk_Rolling_on_Ramp.slx" in the folder ...Examples\2D\Simple\Friction. As usual, the library from Steve is exceptionally documented and I think with this example you will be able to use the blocks in your applications.

But the contact force library does not help much with the leaning of the bike since it considers the wheel as the whole sphere moving along the floor, so is there a way to model the contact force to make the bicycle lean on either sides.
