  1. 6. Adhesion and Friction - a Study on Tactility

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Kenneth Duvefelt; KTH.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adhesion; finger; friction; humidity; material; model; tactile friction; tactility; Machine Design; Maskinkonstruktion;

    Abstract : Although we are surrounded by hundreds of surfaces we can still distinguish them from each other simply by touch. The tactile information, interpreted by our brain and given by our fingers, is precise, but to put words to the sensation is very difficult — is it smooth, sticky or harsh? We do not only perceive surfaces differently, we also describe them in our own way. READ MORE

  2. 7. Tactile Perception - Role of Physical Properties

    University dissertation from Stockholm : KTH

    Author : Lisa Skedung; KTH.; [2010]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Finger Friction; Skin Friction; Paper Friction; Friction Coefficient; Piezoelectric Force Sensor; Skin Tribology; Biotribology; Soft Tribology; Surface Roughness; Profilometry; Coated Paper; Uncoated Paper; Printing Paper; Magazine Paper; Tactile Perception; Psychophysics; Multidimensional Scaling; Magnitude Estimation; Paper Coarseness; Thermal Conductivity; X-ray Photoelectron Spectroscopy.; MEDICINE Chemistry; MEDICIN Kemi;

    Abstract : The aim of this thesis is to interconnect human tactile perception with various physical properties of materials. Tactile perception necessitates contact and relative motion between the skin and the surfaces of interest. READ MORE

  3. 8. The Friction between Paper Surfaces

    University dissertation from Institutionen för pappers- och massateknologi

    Author : Niklas Garoff; KTH.; [2002]
    Keywords : friction; fibers; boundary lubrication; adhesion; capillary condensation; surface forces; chemcial analysis; x-ray photoelectron spectroscopy; atomic force microscope;

    Abstract : The main objective for the work described in this PhD thesiswas to formulate a friction model to characterize thefrictional behavior of paper. More specifically, the modelshould explain a phenomenon that is typical for paper grades,viz.: that the level of paper-to-paper friction is dependent onthe direction and the number of previous slides.

  4. 9. Interface modeling - friction and wear

    University dissertation from Stockholm : KTH

    Author : Anders Söderberg; KTH.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Interfaces; Models; Simulation; Friction; Wear; TECHNOLOGY Engineering mechanics Other engineering mechanics; TEKNIKVETENSKAP Teknisk mekanik Övrig teknisk mekanik;

    Abstract : The general trend toward increased use of computer models and simulations during product development calls for accurate and reliable product models. The function of many products relies on contact interfaces between interacting components. Simulating the behavior of such products requires accurate models of both components and interfaces.
