MARRERO-OSORIO, Sergio A.; ROMERO-VEGA, Alejandro  and  TRIANA-PEREZ, Benigno. Parametric design process of an immersed vibrator applied in a slip-form machine. Ingeniería Mecánica [online]. 2017, vol.20, n.3, pp.136-143. ISSN 1815-5944.

The goal of this paper is to expose the parametric design process of an immersed vibrator, belonging to a horizontal slip-form machine used to prefabricate ferrocement panels. A mathematical model was constructed and validated, which interrelates variables of geometric configuration, mass distribution, excitercharacteristics, stresses and accelerations in remarkable points, Eigenfrequencies, technological operations, energy, costs and other aspects. Based in this model, it was solved the design problem by a method employing dichromatic graphs. For the optimized solution it was iteratively executed a simulation algorithm. To facilitate programming, the simulation algorithm was organized in a particularly advantageous manner for complex systems. As a final result, an optimized design solution was obtained and subjected to physical tests, which demonstrated overcomes previous versions of the vibrating device, so the applied method is appropriated for parametric design of similar devices, when general configuration, functioning principles, forms, and other fundamental aspects, are previously defined. 

Keywords : immersed vibrator; parametric design; mathematical modeling; problem solving; dichromatic graphs; vibration concrete; ferrocement; prefabricated.
