During the MBS Tech Days 2021, Johannes Amberg from the AGCO held a presentation titled "Simpack and FTire in High Horsepower Tractor Applications".

First and foremost, a tractor had to do its job reliably — while driving-comfort taking a back seat. But nowadays, a driver also wants a comfortable driving experience. 
In his presentation, Johannes talks about how tires are a prominent part of the suspension system in tractors. It is impossible to fulfill the simulation scenarios' increasing requirements concerning comfort analysis with our current tire model. Because of this, we started a project together with cosin scientific software, parameterizing a pair of agricultural tires for our 900 series tractors. Because of the large tire sizes, we could not use current tire test rigs to get the tire parameter results. Hence we used a complete tractor as a test bench. To evaluate the tire forces, we set up the tractor with a lot of measurement equipment, especially wheel force transducers. Even though a challenging approach, we found this to be the right way to find a suitable parameterization for our simulation. We now can simulate all of our simulation cases with the generated parameter file for FTire.

@JA studied Mathematics at the Technical University of Munich. After completing his studies in 2006, he joined SIMPACK AG as a project and application engineer. 
In 2012 Johannes joined Fendt, which is part of AGCO. At Fendt, Johannes works within the development department. There he is responsible for the multibody simulation cases as a member of the system simulation team.
