Resumen

The studies about wheels only take in account the samples of big size: car (pneumatic - wheel) or train (non - pneumatic - wheel). However, there is a lack of effort about small structure in this field. In this work is proposed an experimental, low-cost methodology for the characterization of non-pneumatical wheels of small size, typical of roller-skates. Which are usually composed by hyperelastic polymers as PU (Polyurethane). By using a set of small-size 3D printed tools it could be done an impulsive excitation over the structure for an OMA (Operational Modal Analysis) study of the structure. The systematic near-filed measurements in a plane parallel to the wheel can be used to reconstruct and identify the different vibration modes of the structure. Finally, the results have been used to fit a numerical method has been in FEM, with the aim of obtain the apparent physical properties of the different elements of the wheel.
