Analysis of Mechanical Properties of Fabrics of Different Raw Material
Medžiagotyra, 2011 The study analyzes dependence of mechanical properties (breaking force, elongation at break, static friction force and static friction coefficient) on integrated fabric structure factor j and raw material density r, among the fabrics of different raw ...

Carbon Nanotube Based Bearing for Rotational Motions
, 2003 We report the fabrication of a nanoelectromechanical system consisting of a plate rotating around a multiwalled nanotube bearing. The motion is possible thanks to the low intershell friction.

Low Cost Position Controller for Exhaust Gas Recirculation Valve System
Energies, 2018 This paper proposes a position control method for a low-cost exhaust gas recirculation (EGR) valve system for automotive applications. Generally, position control systems used in automotive applications have many restrictions, such as cost and space. The

Holistic Measurement of the Friction Behavior of Wet Clutches
LubricantsThe safe and efficient torque transmission of wet disk clutch systems requires high coefficients of friction. To achieve good controllability and high comfort, a positive slope of the coefficient of friction over sliding velocity is ensured by a ...

The dependence of the dry friction threshold on rupture dynamics
, 2011 The static friction coefficient between two materials is considered to be a material constant. We present experiments demonstrating that the ratio of shear to normal force needed to move contacting blocks can, instead, vary systematically with ...

A new method for landslide safety assessments based on natural vibration frequency
工程科学学报, 2015 Using model experiment, in the condition that the sliding force unchanged, the internal cohesive force and friction force of the slope were analyzed by the natural vibration frequency. The stabilization of landslides was decided by comparing the friction

Extent of force indeterminacy in packings of frictional rigid disks
, 2011 Static packings of frictional rigid particles are investigated by means of discrete element simulations. We explore the ensemble of allowed force realizations in the space of contact forces for a given packing structure.
