RISExperimental Research on Drag Torque for Single-plate Wet Clutch
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The relative motion between the friction and separate plates in a disengaged wet clutch causes viscous drag torque when the lubrication fluid flows through the clearance. Reduction of the drag ...
Optimization Design of Oil Groove Shape on the Surface of Friction Plate in High-Speed Wet Clutch Aimed at Minimizing Drag Torque
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The wet clutch, a crucial component of the vehicle transmission system, experiences high-frequency impact and friction between the friction plate and the steel plate under high-speed separation conditions. This leads to a ...
Impacts of Natural Fractures on Propagation Behaviors of Hydraulic Fractures under Different Pulse Pressures
Publisher: American Society of Civil Engineers
Abstract: AbstractPulse hydraulic fracturing can enhance the productivity of oil and gas wells in low
permeability formations. During pulse hydraulic fracturing, natural fractures significantly
influence the propagation path of ...
Dynamic Analysis of Spiral Groove Rotary Seal Ring for Wet Clutches
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A tribodynamic model of a spiralgroove rotary seal ring is developed through coupling lubrication and dynamic equations. Effects of centrifugation, hydrodynamics, cavitation, and asperity contact are considered. To represent ...

Abstract: Ball piston is an essential design element in eccentric ball piston pump. The objective of this paper is to investigate the dynamic force and lubrication characteristics of the ball piston. In this study, a tribodynamic ...
Additive Manufacturing of Horizontal and 3D Functionally Graded 316L/Cu10Sn Components via Multiple Material Selective Laser Melting
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Production of functionally graded materials (FGMs, i.e., a gradual transition from one material to another) and components is challenging using conventional manufacturing techniques. Additive manufacturing (AM) provides a ...
An Integrated Dual Ultrasonic Selective Powder Dispensing Platform for Three-Dimensional Printing of Multiple Material Metal/Glass Objects in Selective Laser Melting
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we present a new approach of combining point-by-point selective powder delivery with powder bed fusion for multiple material (metal/glass) components printing. Dual ultrasonic vibration was used to achieve ...
Research on the Drag Torque and Power Loss Characteristics of Wet Clutches Based on a Coupled Tribological and Machine Learning Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Drag torque generated in disengaged wet clutches constitutes a critical factor causing power loss, efficiency reduction, and reliability issues in transmission systems. To achieve accurate prediction of drag ...
