  • Chromatic monitoring of gear mechanical degradation based on acoustic emission 

    Delgado Prieto, Miquel; Zurita Millán, Daniel (Institute of Electrical and Electronics Engineers (IEEE), 2017-11-01)
    Article
    Open Access
    This paper presents a methodology for the feature estimation of a new fault indicator focused on detecting gear mechanical degradation under different operating conditions. Preprocessing of acoustic emission signal is ...
  • Disseny d'una roda omnidireccional motoritzada per un AGV industrial 

    Vendrell Pifarré, Joan (Universitat Politècnica de Catalunya, 2013-11)
    Master thesis (pre-Bologna period)
    Open Access
    El següent projecte és el disseny d’una roda especial destinada a usos industrials. Un conjunt de 4 rodes motoritzades especials com aquesta permet el moviment d’un vehïcle amb tres graus de llibertat, és a dir, evita haver ...

    Gámez Montero, Pedro Javier; Antoniak, Piotr; Castilla López, Roberto; Freire Venegas, Francisco Javier; Krawczyk, Justyna; Stryczek, Jaroslaw; Codina Macià, Esteban (2017-09-21)
    Article
    Open Access
    The trochoidal-gear technology has been growing in groundbreaking fields. Forthcoming applications are demanding to this technology a step forward in the conceiving stage of positive displacement machines. The compendium ...
  • Mechanical fault detection by means of AE analysis 

    Zurita Millán, Daniel (Universitat Politècnica de Catalunya, 2013-02)
    Master thesis (pre-Bologna period)
    Open Access
    Rotating machinery is widely used in all of the industrials fields. In this sense, mechanical components are common elements in these systems. Therefore a periodic revision of the mechanical components of the system is ...
  • New solution to prevent excessive wear in wind turbine gears 

    Farré Lladós, Josep; Westerberg, Lars; Casals Terré, Jasmina (Curran, 2014)
    Conference report
    Restricted access - publisher's policy
    During wind turbines operation, yaw and pitch bearings suffer from sequential traction-compression stresses causing millions of micro movements per cycle between the gear teeth. This situation reduces the lubricant thickness ...
  • Numerical study in a mini trochoidal-gear pump with multi-meshing contact points 

    Gámez Montero, Pedro Javier; Castilla López, Roberto; Buza Barambones, Alexis; Khamashta Shahin, Munir Andrawes; Codina Macià, Esteban (American Society of Mechanical Engineers (ASME), 2016)
    Conference report
    Restricted access - publisher's policy
    A numerical study in a mini trochoidal-gear pump based on an ingenious strategy to adapt the background mesh to the profiles shape and a new boundary condition is presented. The strategy achieves a final background mesh ...
