• Numerical Modelling of Structures with Uncertainties

  Publikacja

  • M. Kahsin

  - Polish Maritime Research - Rok 2017

  The nature of environmental interactions, as well as large dimensions and complex structure of marine offshore objects, make designing, building and operation of these objects a great challenge. This is the reason why a vast majority of investment cases of this type include structural analysis, performed using scaled laboratory models and complemented by extended computer simulations. The present paper focuses on FEM modelling...

  - Rok 2014

  Since offshore wind turbine supporting structures are subjected to dynamic environments with time-varying loading conditions, it is important to model their dynamic behavior and validate these models by means of vibrational experiments. In this paper assessment of dynamical state of the structure is investigated by means of both: numerical modeling, and experimental modal analysis. In experimental modal analysis, capturing the...

• Oddziaływania taboru na mosty kolejowe przy zmiennych parametrach ruchu

  Publikacja

  • M. Szafrański

  - Rok 2014

  W pracy poruszono zagadnienia związane z identyfikacją oraz modelowaniem układu dynamicznego most-pojazd ruchomy. Za element szczególnie istotny uznano czynnik obciążający. Opracowano i wdrożono metodykę identyfikacji cech dynamicznych rzeczywistego pojazdu szynowego. Eksperyment badawczy przeprowadzono dla jednostki trakcyjnej EN57, jednak nie ma żadnych ograniczeń w stosowaniu metody dla innego, konwencjonalnego taboru szynowego....

• Strength analysis of a large-size supporting structure for an offshore wind turbine

  Publikacja

  • K. Niklas

  - Polish Maritime Research - Rok 2017

  The offshore wind power industry is the branch of electric energy production from renewable sources which is most intensively developed in EU countries. At present, there is a tendency to install larger-power wind turbines at larger distances from the seashore, on relatively deep waters. Consequently, technological solutions for new supporting structures intended for deeper water regions are undergoing rapid development now. Various...

• Analysis of Modal Parameters Using a Statistical Approach for Condition Monitoring of the Wind Turbine Blade

  Publikacja

  • Ł. Doliński
  • M. Krawczuk

  - Applied Sciences-Basel - Rok 2020

  The primary objective of the presented paper is the numerical and experimental investigation related to developing a useful diagnostic method, which can be used for determining the site and size of damage in laminated shells of wind turbine blades. The described detection technique is based on the analysis of low frequencies bending vibrations mode shapes of rotor blades. The authors used the commonly applied statistics methods...
