  1. 16. Simulation of contact, friction and wear in gears : a finite element approach

    University dissertation from Linköping : Linköpings universitet

    Author : Olle Lundvall; Linköpings universitet.; Linköpings universitet.; [2000]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gears; Gear noise; Contact mechanics; Simulation; Friction; Wear; Transmission error;

    Abstract : In this thesis, resent methods in computational contact mechanics is brought into the process of gear design. The finite element method is used to model two elastic bodies in contact. By defining a contact interface between these two bodies, constitutive laws, regarding normal contact, friction and wear, are included. READ MORE

  4. 19. Friction and contact phenomena of disc brakes related to squeal

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Mikael Eriksson; Uppsala universitet.; [2000]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Tribology; contact mechanics; squeal; brake pad; disc brake; friction; Materialvetenskap; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap; materialvetenskap; Materials Science;

    Abstract : Brake squeal is a sound with a main frequency between 1 and 20 kHz, generated by an oscillation of the components of the brake system. The energy driving the oscillation is supplied by the friction between the disc and the pads. READ MORE
