VIBRATION AND STABILITY PROBLEMS OF MAGNETICALLY SUSPENDED VEHICLES DURING INTERACTION WITH FLEXIBLE TRACKS. MODELLING ELASTICITY IN A MULTIPLE BODY VEHICLE, DESCRIPTION OF RIGID AND FLEXIBLE CONNECTIONS, FORMULATION OF THE INTERACTION DURING HOVERING AT A STANDSTILL

IN ORDER TO SIMULATE MAGNETICALLY SUSPENDED VEHICLES, INCLUDING THEIR INTERACTION WITH FLEXIBLE TRACKS, THERE IS A NEED FOR COMPLEX MATHEMATICAL MODELS AND PROGRAMS DERIVED FROM THEM. SUCH A SUITE OF PROGRAMS WAS DEVELOPED AT THE DFVLR. DETAILS ARE GIVEN OF THE MODELLING OF THE ELASTICITIES IN THE VEHICLE AND AN ESTIMATION MADE OF THE DEGREE OF VEHICLE FREEDOM NEEDED FOR SIMULATION. THE STABILITY OF THE VEHICLE AND STRUCTURE WHILE HOVERING AT A STANDSTILL IS ALSO CONSIDERED.
