Triboelectric nanogenerators for vehicle intelligent cockpits

FlexMat, EarlyView.
Converting mechanical stimuli from drivers and vehicle motion into electrical signals, triboelectric nanogenerators provide promising interfaces toward passive, flexible, distributed and intelligent sensing for next‐generation automotive cockpits to support three core functional dimensions: driver state monitoring, vehicle state monitoring, and human ...

Residual stress field of HIPed silicon nitride rolling elements [PDF]

, 2002
The residual stress field of HIPed Si3N4 rolling elements were studied. Two kinds of HIPed Si3N4 ball blanks self-finished at different nominal lapping loads ranging from 1.3 to 10.87 kgf/ball and four kinds of commercially finished 1/2 in (12.7 mm ...

Mechanics of longitudinal rolling of tube through three-grooved rolls [PDF]

, 1984
This investigation examined the process of the longitudinal rolling of tubes through a set of three driven grooved rolls. Tubes were rolled with or without internal support i.e. under mandrel rolling or sinking conditions. Knowledge was required of the way in which the roll separating force and rolling torque vary for different conditions of rolling ...

Illuminating point‐of‐care diagnostics with aggregation‐induced emission biosensors

FlexMat, EarlyView.
This review highlights the application of aggregation‐induced emission luminogens (AIEgens) in point‐of‐care (POC) diagnostics for disease biomarker detection. It systematically examines a range of biosensing platforms, including lateral flow immunoassays, microfluidic chips, and electrochemiluminescence sensors, alongside their utility in detecting ...

Visualization of oil-lubrication ball bearings at high rotational speeds

Frontiers in Mechanical Engineering
Deep-groove ball bearings for the eAxles of electric vehicles must adapt to higher rotational speed conditions because the speed of eAxle motors have been increasing as the size and weight of the motors decrease.

Optimization of groove design for rolling of long products

, 2003
By using FE calculations and the program module LS-OPT, the optimal input geometry for a given groove design can be calculated. Quantitative values for the sensitivity to dimensional variations are calculated and can be used to optimize the tolerances at

FE-Modeling of Cold Rolling by In-Feed Method of Circular Grooves

Strojniški vestnik – Journal of Mechanical Engineering, 2011
The methods of cold rolling of rods are widely used in manufacturing industries to obtain pieces with complex profiles. In this study, complex profiles with grooves have been formed by in-feed methods using two rolls. An experimental system was constructed to record the process parameters. The microhardness has been measured by the Vickers method in an

Transforming Agricultural Water Management for Healthy People and Planet: Thinking Beyond Water

Irrigation and Drainage, EarlyView.
ABSTRACT This paper develops the concept of Thinking Beyond Water, a transdisciplinary paradigm that reframes agricultural water management (AWM) as a systems catalyst for planetary health, equity, justice and resilience. Moving beyond conventional irrigation‐centric models, we reimagine AWM through integrative frameworks such as the planetary ...

Flattening of Surface Grooves in Cold Flat Rolling

Procedia Engineering, 2014
AbstractIn sheet rolling, surface deforms more than bulk interior so that surface asperities are flattened. However, it is still not easy to predict the roughness of the sheet after rolling. Copper sheets having artificial triangular grooves running either in the transverse or the rolling direction were cold-rolled.
