Investigation of engagement characteristics of a multi-disc wet friction clutch

Tribology International, 2021
Abstract A kinematic coupling model of the rotation-axial engagement process of friction elements is established based on the oil film dynamic pressure lubrication and an elastic contact model of the asperities. The engagement characteristics of the multi-disc wet friction clutch are analyzed. The equation for the transmission torque of the clutch is

Estimation of the Clutch Characteristic Map for an Automated Wet Friction Clutch Transmission

SAE Technical Paper Series, 2016
<div class="section abstract"><div class="htmlview paragraph">Higher demands on comfort and efficiency require a continuous improvement of the shift process. During the launch and shift process the clutch control is used to get a smooth and efficient behavior. In this short time of acting the shifting behavior can be rated.

Modeling and analysis of wet friction clutch engagement dynamics

Mechanical Systems and Signal Processing, 2015
Abstract In recent years, there has been a significant increase in the usage of wet-friction clutches. Presently researchers across the globe are involved in improving the performance and lifetime of clutches through testing and simulation. To understand the clutch vibrational and dynamical behavior, an SAE#2 test setup mathematical model based on ...

Engagement behavior of degrading wet friction clutches

2011 IEEE/ASME International Conference on Advanced Intelligent Mechatronics (AIM), 2011
This paper presents modeling, simulation and experimental validation of the friction material degradation effects on the dynamic engagement behavior of a wet friction clutch system. The clutch system is modeled as a 3 DOF lumped-mass-spring-damper incorporating an extension of the Generalized Maxwell Slip (GMS) friction model.

A simplified wet friction clutch test apparatus

Tribotest, 1995
AbstractA small, economic, test rig to evaluate friction materials and fluids for wet clutch applications has been designed, built and commissioned. In this paper, the construction, operation and performance of the machine are described, and results are presented, for two sets of typical tests.
