FREIGHT CAR DYNAMICS--ONE CARBUILDER'S APPROACH

Amcar Division of ACF Industries, like the other carbuilders, is taking on additional responsibilities for all aspects of car dynamics design and test, particularly with respect to carbody structure. Explained is the ACF computerized system for analysis of carbody structural dynamics, intended to combat fatigue problems. Mathematical modeling is used to develop load paths and stress profiles of complex structures. Road testing is important in developing environmental data and ACF has acquired an instrument car for this purpose. Modified Goodman Diagrams are developed and their use is discussed.
