LINDA 1: A PROGRAM SYSTEM FOR INVESTIGATION OF THE DYNAMIC BEHAVIOR OF RAILWAY VEHICLES

LINDA 1 - EIN PROGRAMMSYSTEM ZUR UNTERSUCHUNG DES DYNAMISCHEN VERHALTENS VON SCHIENENFAHRZEUGEN

A computer program is introduced which helps to establish linearized differential equations of motion schematically for any railway vehicle by an element procedure. Apart from the usual elements like springs, masses, and dampers, rigid connecting elements as well as specific railway vehicle elements (e.g. wheel sets) are introduced. At present, conservative and non-conservative eigenvalues and eigenvectors can be calculated by this program. The graphical output of speed dependent eigenvalues as root loci is demonstrated.
