  • Durability evaluation of technical fabrics

    Publication

    - Year 2013

    A thorough examination of the influence of the conditions of use on the mechanical properties of technical fabrics is proposed. Laboratory experiments (uniaxial tensile, rheological, cyclic and biaxial tensile tests) have been conducted and the material’s parameters for Finite Element Method (FEM) simulations have been identified. Various constitutive models of technical fabrics are investigated and compared. On the basis of these...

  • Determination of CWR track's durability characteristics

    Publication

    - Year 2005

    W pracy przedstawiono wyniki badań nad wyznaczaniem sił osiowych w szynie kolejowej z zastosowaniem metody wymuszonych przemieszczeń poprzecznych. Badania przeprowadzone na stacjonarnym stanowisku badawczym wykazały, że siłę podłużną w szynie można znacznie dokładniej określić na podstawie zmiany nie pionowej, lecz poziomej siły poprzecznej. Pozwoliło to właściwie ukierunkować prace nad określaniem sił osiowych w szynach toru...

  • A method for evaluating durability of porous slide bearings

    Publication

    The article presents the structures of porous bearings bushes and greasy lubricants, and the similarity criterion resulting from this structures. A phisical model is proposed which describes the operation of the porous slide bearing bush taking into account, via analogy, the phenomena taking place in the grease lubricant nodes instead of those observed in the bush structures.Included are the result of experimental tests of three...

  • Testing the durability and function of road traffic management devices

    Publication

    - MATEC Web of Conferences - Year 2017

    Traffic management measures (vertical signs and horizontal marking, reflective elements) are used for guiding vehicles optically, indicating road mileage, marking objects in road gauge, marking vehicle and pedestrian safeguards and driver information and warning. This paper presents a synthesis of a literature study and the results of research conducted under stage one of the project LifeRoSE. The requirements for different traffic...
