VERTICAL VIBRATIONS OF VEHICLES WITH PRIMARY AND SECONDARY SUSPENSIONS

SUR LES VIBRATIONS VERTICALES D'UN VEHICULE COMPORTANT DEUX ETAGES DE SUSPENSION

This doctorate's thesis is a mathematical study of the dynamic behavior of a rail vehicle: it examines the vibratory system constituted by the underframe resting on elastic supports with two-tier suspension, and discusses the equation models and results calculated by means of a digital computer. Study of the curves reproduced on tracing tables, and of the influence of the different vehicle-construction parameters makes it possible to assess the incidence of the geometrical characteristics of a steel body, the influence of the suspension on vertical behavior and the desirable damping value for optimizing passenger comfort.
