Multibody simulation of a small size farming tracked vehicle

In this paper, the Multibody (MTB) model of a small size tracked vehicle for farming applications is shown. These machines may encounter several working scenarios in their operating life when equipped with different working tools. Moreover, they are used in unstructured environments that are very difficult to predict in terms of terrain conditions and slope. Depending on these factors, the actual tractive force may vary a lot requiring often a high number of field tests to qualify the vehicle performance. The numerical model built in MSC ADAMS, wants to be a software environment where several working conditions can be exploited considering the dynamic properties of the vehicle. This work focuses on the global kinematic behavior, considering the difference between imposed motion laws and the actual one.
