Conceptual Design of a 3 Wheeler Motorbike – Load Extraction through Multibody Simulation

In the following project phase we wonder about the forces/moments acting on the frame if the bike is steered across a curbstone. Of course, our model and the assumptions made represent an oversimplification of reality, nevertheless, the videos should give you a better understanding on how to extract (these) loads by means of  Multibody Simulation.
