THE FEASIBILITY OF THE DETERMINATION OF RIGID/ELASTIC IMPACT LOADS BETWEEN STRUCTURES WITH THE METHOD OF MODE SUPERPOSITION

In this paper,the problem of both the lateral and the logitudinal impactof bars is investigated.The feasibility of the dertermination of rigid / elastic impact loadsbetween structures with the method of mode superposition is verified。A numerical integra-tion method is developed to evaluate the time history of the impaact load , and the obtainedresults are analyzed and interpreted through the use of the theories of wave propagation,elastic contact and vibration modes。The accuracy and utility of the given me...
