Sažetak
The procedure for numerical analysis of the elastic impact of two beams is presented. The beams are modelled by using the FEM technique, and for time integration of dynamic equilibrium equation the modified linear acceleration method is applied. Special attention is paid to contact problem and to calculation execution. Short review of the energy conservation principle based method for impact force determination is also given. The procedure is illustrated with the case of collision of communication bridge between two offshore platforms and the protective construction, called arrestor. The results are compared to those obtained by energy conservation principle based method. The study of damping influence on system dynamic response is also added.
