Articles you may be interested in Velocity dependence of friction and Kramers relaxation rates Is slow thermal isomerization in viscous solvents understandable with the idea of frequency dependent friction? We present new data on the ground state isomerization rate of DODeI and compare our results to previously obtained excited state data. We find that the one-dimensional Kramers expression doe...
Background: Lateral epicondylalgia of Humerus is the most common type of overuse injuries with different methods of treatment controversial. This randomized clinical trial aims to evaluate the effectiveness of Cyriax deep friction massage versus Ultrasound (US) plus passive stretching on lateral epicondylalgia. Methods : In this study, patient with more than 6 weeks pain in lateral epicondy...
A brake hardware-in-the-loop simulation (HILS) system for a railway vehicle is widely applied to estimate and validate braking performance in research studies and field tests. When we develop a simulation model for a full vehicle system, the characteristics of all components are generally properly simplified based on the understanding of each component's purpose and interaction with other compo...
Submitted for the MAR05 Meeting of The American Physical Society Preparation and Friction Property of Dendritic Thin Film QING ZHANG, LYNDEN ARCHER, Cornell University — To investigate the effect of film structure on their friction properties, thin films with dendritic structure were prepared on silicon surfaces by step-growth propagation, and their friction properties were studied by AFM. The ...
In this paper, we deal with the problem of time-optimal trajectory planning and feedforward controls for robotic manipulators along predetermined geometric paths. We propose a convex relaxation to generate time-optimal trajectories and feedforward controls that are dynamically feasible with respect to the complete nonlinear dynamic model, considering both Coulomb friction and viscous friction. ...
