    Occurrence of strick-slip phenomenon.
    (Polskie Towarzystwo Mechaniki Teoretycznej i Stosowanej, 2007) Awrejcewicz, Jan; Olejnik, Paweł
    A self-excited system wit h unilateral friction contact modelled by a two degrees-of-freedom mechanical system, where the normaI farce varies during displacement of a block has been studied. The constructed real laboratory rig approximates the investigated system, and it includes feedback reinforcement of the friction force acting on the vibrated block. Some methods of data acquisition and data handling procedures are proposed for experimentally observed results and data collection. A novel static friction force model for both positive and negative velocities of the base is proposed.
