SUSPENSION DYNAMICS, VOLUME 1. TRUCK SUSPENSION

This study is a further extension of the Harmonic Roll Series case studies reported on by Track Train Dynamics, Phase I, in Volumes I to IV (R-172, R-173, R-174, and R-184). It is essentially the first part of an extensive parametric study to be conducted during Track Train Dynamics, Phase II. This study, similar in scope to the previous investigations, concerns itself with the roll problem as well as the bounce phenomenon. The purpose of the work contained herein is to aid car and truck designers by showing the effects of changes in various parameters on roll and bounce behavior. In some instances computer simulations are the only method which can be used to check performance; i.e., checking wheel lift and other tendencies. Obviously, for safety reasons, field testing of potentially dangerous conditions would be precluded.
