Influence of Clutch Output Shaft Inertia and Stiffness on the Performance of the Wet Clutch
Tribology Transactions, 2013 Being a part of the complex mass, spring, and damper system in a driveline, the choice of design factors such as output shaft stiffness and inertia of a wet clutch system can influence its performance. The effects of these parameters were experimentally evaluated.

Wet Single Clutch Engagement Behaviors in the Dual-Clutch Transmission System
International Journal of Automotive Technology, 2018A frictional torque was generated by a lubricated slip contact between a wet clutch pad and a steel separator during a wet clutch engagement. It is necessary to understand the generation of frictional torque to improve the performance of the frictional torque transfer and the durability of the wet clutch system.

The mechanisms of wet clutch friction behaviour [PDF]
, 2010 Wet clutches are used in automatic transmissions to bring about gear changes and also to reduce energy loss in the torque converter. These friction devices are susceptible to stick-slip effects, which result in the vehicle giving an unsteady ride. Stick-slip effects can be avoided by ensuring the wet clutch and lubricant combination produces a friction

Water contamination effect in wet clutch system
Proceedings of the Institution of Mechanical Engineers, Part D: Journal of Automobile Engineering, 2012 Water contamination in wet clutch systems can be a problem since both torque characteristics and wear resistance can be influenced by the presence of water. The present paper reveals the effect of externally added water on the wet clutch frictional performance.

Wet clutch under limited slip conditions - simplified testing and simulation
Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology, 2007 When designing new wet clutch systems, simulations and laboratory tests are important to obtain a functional system. An engineering tool is here developed to simulate wet clutches working under boundary lubrication conditions.

Wet Clutch Drag Loss Simulation for Different Clutch Patterns
SAE Technical Paper Series, 2022<div class="section abstract"><div class="htmlview paragraph">Wet clutches drag loss simulation is essentially linked to the clutch friction surface patterns in addition to the main geometry and conditions of the interface (relative speed, separation, inner and outer radius, viscosity and boundary pressures).

Thermal Characteristics of a Wet Clutch
Journal of Tribology, 1999A comprehensive formulation of the governing equations, boundary conditions, and numerical solution technique is presented for modeling the thermal aspects of the engagement process in a wet clutch. The thermal model includes full consideration of the viscous heat dissipation in the fluid as well as heat transfer into the separator, friction material ...

On the Behaviour of Scalarization Methods for the Engagement of a Wet Clutch
2013 12th International Conference on Machine Learning and Applications, 2013Many industrial problems are inherently multi-objective, and require special attention to find different trade-off solutions. Typical multi-objective approaches calculate a scalarization of the different objectives and subsequently optimize the problem using a single-objective optimization method.

Pressure Estimation of a Wet Clutch
2014In both DCTs and new ATs, the change of the speed ratio is regarded as the process of one clutch being engaged with the other being disengaged, namely, the clutch-to-clutch shift. For vehicles with a hydraulic cylinder as clutch actuator, the cylinder pressure control is important for good shift quality.
