    • A simplified methodology to evaluate the design specifications of hydraulic components 

      Roquet, Pedro; Gámez Montero, Pedro Javier; Castilla López, Roberto; Raush Alviach, Gustavo Adolfo; Codina Macià, Esteban (Multidisciplinary Digital Publishing Institute, 2018-09-11)
      Article
      Open Access
      The fatigue of a hydraulic component inherently varies due to various factors that can be divided into two categories: structural and load spectrum variability. The effects of both variabilities must be considered when ...

      Roquet, Pedro; Raush Alviach, Gustavo Adolfo; Bernè Artieda, Luis Javier; Gámez Montero, Pedro Javier; Codina Macià, Esteban (2022-02-14)
      Article
      Open Access
      Mobile machinery manufacturers must face and deal with reducing fuel consumption, rising prices, and environmental pollution. The development of methods to evaluate the efficiency and effectiveness of the energy performance ...
    • Graphic method to evaluate power requirements of a hydraulic system using load-holding valves 

      Berne, Luis Javier; Raush Alviach, Gustavo Adolfo; Roquet, Pedro; Gámez Montero, Pedro Javier; Codina Macià, Esteban (2022-07-01)
      Article
      Open Access
      It is very well known that the use of a load-holding valve (LHV) in a hydraulic system introduces additional energy consumption. This article presented a simplified graphical method for analyzing the power requirements of ...
    • Pressure-drop coefficients for cushioning system of hydraulic cylinder with grooved piston: a computational fluid dynamic simulation 

      Castilla López, Roberto; Alemany, Ignasi; Algar, Antonio; Gámez Montero, Pedro Javier; Roquet, Pedro; Codina Macià, Esteban (2017-10-25)
      Article
      Open Access
      Cushioning is an important aspect in hydraulic cylinder performance. The piston has to be decelerated before it strikes the end cap in order to avoid stresses in the cylinder components and reduce vibration that can be ...
