The present paper aims to analyze the dynamic behavior of the 6x6 IVECO M250.45 WM truck, which is currently in the endowment of the National Ministry of Defense. Therefore, both the truck and a military standardized testing track will be modeled in a simulation software. The study will take in consideration the measuring of the maximum speed that the vehicle can achieve off-road before roll-over, an important piece of data for military applications. The study through simulation presents multiple advantages such as low costs and a variety of possible tests. Thus, this paper could serve in future as a support for experimental research.
