This paper proposes a generic model for agricultural tractor able to study the variation of energy level absorbed by Roll-Over Protective Structure (ROPS) during an impact induced by rollover situation with respect to several parameters (mass, shape, environment, ). In relationship with the origin of the tractor cabin testing procedure detailed by the Organisation for Economic Co-operation and Development (OECD), such a model (designed using the simulation software Adams) allows the simulations of hazardous situations for impact energy calculation. Based on this material, a sensitivity study of this energy variation is proposed and compared to the standard provided by official testing procedure in order to check its relevance with respect to current tractor design. The results presented in that paper allow to define some theoretical limits to the applicability of ROPS Code 4 and open the way to some update for a better correlation between testing procedure and tractor design evolution.
