    Article
    Accés obert
    The work presented in this article demonstrates the use of an empirical and simplified approach based on an optical technique and a home-made ad hoc code that give knowledge of the shape and falling velocity of a free-falling ...
  • Bond graph simulation of error propagation in position estimation of a hydraulic cylinder using low cost accelerometers 

    Algar, Antonio; Codina Macià, Esteban; Freire Venegas, Francisco Javier (2018-10-01)
    Article
    Accés obert
    The indirect calculation from acceleration of transversal displacement of the piston inside the body of a double effect linear hydraulic cylinder during its operating cycle is assessed. Currently an extensive effort exists ...
  • Computational fluid dynamics and particle image velocimetry assisted design tools for a new generation of trochoidal gear pumps 

    García Vilchez, Mercedes; Gámez Montero, Pedro Javier; Codina Macià, Esteban; Castilla López, Roberto; Raush Alviach, Gustavo Adolfo; Freire Venegas, Francisco Javier; Río Cano, Carlos (2015)
    Article
    Accés obert
    Trochoidal gear pumps produce significant flow pulsations that result in pressure pulsations, which interact with the system where they are connected, shortening the life of both the pump and circuit components. And this ...
