Power Train - Vehicle Modeling to Simulate Shifting Transients ofoff - Highway Vehicles

摘要

Analytic modeling and analog computer simulation techniques are presented to determinethe power train transient responses excited by clutch-actuated gear shifts.A method to describe thedynamics of a transmission arrangement having several clutches and interconnected planetary gearsets is considered in detail.Simulation model testing is directed toward optimizing system designparameters and evaluating power train component capability and vehicle shift-feel.Data reductiontechniques applied to model responses of torque and speed will yield appropriate spectrumsrepresentative of simulated work cycle.
