Machines, 2023 Generally speaking, excessive side thrust and roller slippage are two different aspects affecting cam-roller mechanisms. In novel large-scale hydraulic drivetrains for offshore wind turbines, the highly dynamic nature of these mechanisms combined with ...

The Effect of Pre-Stretched Substrate on the Electrical Resistance of Printed Ag Nanowires
Nanomaterials, 2023 One-dimensional nanomaterials have drawn attention as an alternative electrode material for stretchable electronics. In particular, silver nanowires (Ag NWs) have been studied as stretchable electrodes for strain sensors, 3D electronics, and freeform ...

Microscale friction reduction by normal force modulation in MEMS. [PDF]
, 2010 Friction in MEMS-scale devices is troublesome because it can result in lateral stiction of two sliding surfaces. We have investigated the effect of modulation of the normal force on the friction between two sliding MEMS surfaces, using a fully MEMS-based

Thermal imaging on simulated faults during frictional sliding [PDF]
, 2006 Heating during frictional sliding is a major component of the energy budget of earthquakes and represents a potential weakening mechanism. It is therefore important to investigate how heat dissipates during sliding on simulated faults. We present results

Peeling and Sliding in Nucleosome Repositioning
, 2007 We investigate the mechanisms of histone sliding and detachment with a stochastic model that couples thermally-induced, passive histone sliding with active motor-driven histone unwrapping.

Dependence of boundary lubrication on the misfit angle between the sliding surfaces
, 2010 Using molecular dynamics based on Langevin equations with a coordinate- and velocity-dependent damping coefficient, we study the frictional properties of a thin layer of "soft" lubricant (where the interaction within the lubricant is weaker than the ...

Optimal sliding mode controllers for attitude tracking of spacecraft [PDF]
, 2009 This paper studies two optimal sliding mode control laws using integral sliding mode control (ISM) for some spacecraft attitude tracking problems. Integral sliding mode control combining the first order sliding mode and optimal control is applied to ...

Sliding states of a soft-colloid cluster crystal: Cluster versus single-particle hopping [PDF]
, 2018 We study a two-dimensional model for interacting colloidal particles which displays spontaneous clustering. Within this model we investigate the competition between the pinning to a periodic corrugation potential, and a sideways constant pulling force ...
