Power Train-Vehicle Modeling to Simulate Shifting Transients of Off-Highway Vehicles

Abstract:

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