Analysis of start-up transient for a powertrain system with a nonlinear clutch damper
Develop and experimentally validate a new 4DOF nonlinear powertrain model for transient events within the clutch damper and transmission during the engine start-up. Correlate the interactions between multiple transient events using new metrics. Examine nonlinear characteristics and find the transient envelope of the clutch damper using harmonic balance method for a slowly varying process. Develop analytical formulas to approximate the transient amplification for a rapidly varying process.
