A Calibration Optimizer Tool for Torque Estimation of

2017-5-1Modelling and clutch characterization help tackle some of the challenges posed Consider a sample pressure command applied to a typical hydraulic clutch as shown in Figure 2 The actual apply pressure on the clutch would typically respond as shown in the same figure

Friction Behavior of a Wet Clutch Subjected to

This study aims at experimentally investigating the sliding friction characteristics of a wet clutch during its lifetime More precisely the objective is to understand how the Stribeck and the frictional lag (i e sliding hysteresis) parameters evolve as the clutch degradation progresses For this purpose a novel test procedure has been proposed and a set of experiments has been carried out

A Simplified Approach to Modeling Thermal Effects in

The simplified isothermal model for wet clutch engagement previously developed by Berger Sadeghi and Krousgrill (Berger E J Sadeghi F and Krousgrill C M 1996 "Analytical and Numerical Modeling of Engagement of Rough Permeable Grooved Wet Clutches " ASME J Tribol 119 p 143) was extended to include fluid thermal effects The modified Reynolds and thermal diffusion
