Rekenmodellen van de RIMOB : een beschrijving van rekenmodellen voor de bepaling van de energieabsorptiecapaciteit en zijdelingse stabiliteit van de rimpelbuisobstakelbeveiliger (RIMOB).

In an earlier report the development and tests of the RIMOB (an impact attenuator with crumpling tubes) were described. See B 22165 (IRRD 269921). In this report the mathematical models are described which can determine the energy absorption capacity and the stability of the RIMOB. The models are only developed for frontal collisions of the RIMOB. Two mathematical models are developed. One model for the determination of the energy absorption capacity of the RIMOB, is based on frontal, central collisions and the other model is based on oblique angle collision on the nose of the RIMOB. The models are based on the energy balance: the kinetic energy of the colliding vehicle is fully absorbed by the RIMOB. The models are very pragmatic.
