Modeling and analysis for simulation of vehicle chassis motion during powertrain engagement/gear shift events

摘要

Noise and vibration generated during powertrain clutch engagement/gear shift has been a major factor that influences ride quality perception. The abrupt heave and pitch motion induced in chassis is especially discomforting. Although this undesirable motion could be minimized through optimal suspension/powertrain design, in reality it is often unobtained due to its cross-functional nature of the design effort.
