Friction-induced vibration in the wiper system of passenger cars not only causes impaired visibility as a result of uneven water film distribution on the windscreen surface, but also leads to noise problems by transmitting vibrations as sound to the

The authors have previously developed the electrical impedance method which simultaneously measure the thickness and breakdown ratio of oil films in EHD (elastohydrodynamic) contacts. Furthermore, using a ball-on-disc-type apparatus, the authors have

It is well known that the friction coefficient of viscoelastic solids against the drive speed exhibits a bell shape. In previous theoretical studies on viscoelastic friction, we can find two origins for the bell shape. One is due to the material resp

This paper reports the thermally activated ultralow friction of 100% cellulose nanofiber (CNF) molding. The mechanism of friction reduction was investigated using a laboratory-built in-situ Raman tribometer. Our experimental results showed that a CNF

Experimental results on the reaction of Cardiac Spheroids – spherical clusters of cardiac cells – obtained and studied recently by Nakano et al. are interpreted in the framework of a model of cardiac tissue as an unstable medium with retardation.

Chain continuously variable transmissions (chain CVTs) are known as promising technology due to their high torque capacity. However, they generate noise and vibration problems due to their flexible structure. The present study aimed to address these

Recent advances in computational methods have enabled realistic numerical simulations for the sliding friction of viscoelastic solids (e.g., rubber friction by the finite element method in the macroscale and soft matter friction by the molecular dyna

Concentrated polymer brushes (CPBs) synthesized by advanced surface-initiated controlled radical polymerization have received increasing attention in the tribological field because CPBs in good solvents exhibit superlow friction phenomena under macro

Suitable friction modifiers and anti-wear additives for hydrogenated amorphas carbon (a-C:H) films have been investigated by many research groups for a decade since it is well-known that the combination of the a-C:H film and the conventional additive

Abstract Adsorbed molecular films, referred to as boundary films in tribology, are widely used in various industrial products as a keyway for surface functionalisation, such as lubricity, wettability, and adhesion. Because boundary films are thin nan
