Simplified model for the study of the asymmetric rocking motion of slender rigid bodies

Peña, F.
This paper deals with the numerical modelling of rigid blocks by means of a rigid body spring model (RBSM). The hypothesis of small rotations has been considered in order to simplify the mathematical formulation. The asymmetric rocking motion is described. Extensive numerical simulations have been carried out in order to validate the numerical model, as well as to study the dynamical behaviour of asymmetric rigid bodies. The maximum response depends on the type of asymmetry and the direction of the load, which should become new variables in the study of asymmetric rocking motion.
