• Analytical Study of Sliding Instability due to Velocity- and Temperature-Dependent Friction

  Publikacja

  • O. Nosko

  - TRIBOLOGY LETTERS - Rok 2016

  The instability of sliding causes deterioration of performance characteristics of tribosystems and is undesired. To predict its occurrence, the motion of a body of a one-degree-of-freedom system with friction is investigated about the steady sliding equilibrium position. The motion equation is formulated with the friction coefficient dependent on the sliding velocity and contact temperature changing due to transient heat conduction...

• STABILITY ANALYSIS OF A TRUSS WITH SLOPING ELASTIC BRACES

  Publikacja

  • P. Iwicki
  • M. Krajewski

  - Rok 2014

  Steel trusses have a much greater strength and stiffness in their plane than out of their plane, and therefore should be braced against lateral deflection and twisting. Such elements like purlins apart from bearing vertical load are part of bracing that stabilize roof trusses against distortional buckling. The stability of trusses with elastic bracing was investigated in an experimental research. Braces situated at some angle measured...

• A New Fuzzy Sliding Mode Controller with PID Sliding Surface for Underwater Manipulators

  Publikacja

  • H. Nejatbakhsh Esfahani

  - Rok 2013

  Design of an accurate and robust controller is challenging topic in underwater manipulator control. This is due to hydrodynamic disturbances in underwater environment. In this paper a sliding mode control (SMC) included a PID sliding surface and fuzzy tunable gain is designed. In this proposed controller robustness property of SMC and fast response of PID are incorporated with fuzzy rules to reduce error tracking. In the control...

• Analysis of sloping brace stiffness influence on stability and load bearing capacity of a truss

  Publikacja

  • M. Krajewski
  • P. Iwicki
  • N. Dorożyńska
  • A. Łukowicz

  - Rok 2016

  The paper is focused on the numerical study of stability and load bearing capacity of a truss with side elastic braces. The structure is made in reality. The rotational and sliding brace stiffnesses were taken into account. Linear buckling analysis and non-linear static analysis with geometric and material nonlinearity were performed for the beam and shell model of the truss with respect to the angle of sloping braces. As a result...

• Dry bearing sliding layer transverse flexibility effects on real sliding distance for reciprocating microoscillatory movement of flatcontact surface.

  Publikacja

  • R. Gawarkiewicz

  - Rok 2004

  W referacie omówiono wpływ właściwości mechanicznych i kształtu warstwy ślizgowej z bezsmarowego materiału łożyskowego. Wcześniej omówione i publikowane wyniki badań doświadczalnych i analizy numerycznej wyjaśniły i potwierdziły, dlaczego rzeczywista droga tarcia jest znacznie mniejsza od nominalnej w warunkach mikrooscylacji. Wyniki przeprowadzonej analizy numerycznej pozwoliły możliwie najlepiej ukształtować powierzchnię ślizgania...

• Friction induced vibrations in sliding of monolithic alumina

  Publikacja

  • J. Łubiński
  • K. Druet

  - Rok 2005

  Przedstawiono wyniki badań wzbudzania się (i ewentualnie - zaniku) drgań mechanicznych towarzyszących tarciu ślizgowemu próbek o płaskiej powierzchni styku, wykonanych z monolitycznego tlenku aluminium. Badano wpływ wymuszeń tribologicznych oraz dynamicznych cech układu badawczego na przebieg zjawiska.

• Performance of lubricated sliding contact in magnetic field

  Publikacja

  • T. Stolarski
  • Y. Makida

  - TRIBOLOGY LETTERS - Rok 2012

  Results of experimental studies concerning theinfluence of permanent magnetic field on wear of lubricatedsliding contact operating at short stroke and highfrequency are presented. It was found that horizontalmagnetic is affecting performance of the contact. Thejagged delamination regions produced in the presence of amagnetic field can be regarded as easily undergoing oxidisationbecause oxygen is readily adsorbed there. Magneticfield...
