STIFFNESS ESTIMATION METHOD FOR THE DISCRETIZED DYNAMIC MODEL OF RAILWAY CAR BODIES

Abstract

A method has been presented for the algorithmized estimation of equivalent secondorder moments involved in the discretized model of railway car bodies. Assuming the deflection function of the continuum model to be kno\wn, the objective function to be minimized as well as the rnethod of numerical solution are described. Application of the method is illustrated on hand of a test problem.
