FREIGHT CAR TRUCK DESIGN OPTIMIZATION. VOLUME V. CRITIQUE OF FREQUENCY DOMAIN MODEL-EQUATIONS OF MOTION

As part of the Truck Design Optimization Project (TDOP) a mathematical model was developed to be used for predicting truck behavior. The model, its description, the nomenclature used, and the development of the equations of motion were all oriented toward the computer program which would ultimately solve the equations. A detailed review and evaluation of the mathematical model was carried out. This review was judged necessary to provide an independent evaluation of the model which contained many assumptions and some errors whose effect was not clear.
