El Dr. Alberto Pertuz, PhD, profesor de la Escuela de Ingeniería Mecánica e investigador del grupo GIEMA, a obtenido la patente para MÁQUINA DE FATIGA MULTIAXIAL, WO2018116092 (A1) ― 2018-06-28.
Abstract: The present invention corresponds to a multiaxial fatigue machine which comprises a rotational mechanism, formed by a first driving shaft with a first end connected to a first motor via a first coupling element; and a second end connected to a first attachment element. In addition, the rotational mechanism has a driven shaft arranged in alignment with the first driving shaft. Said driven shaft has a first end connected to a stationary bearing, and a second end connected to a second attachment element. The second attachment element is arranged in alignment with the first attachment element, and a second coupling element which connects the first end with the second end. In addition, the machine has a reciprocating mechanism which has a second driving shaft connected to a second motor, and a rotational-linear transmission connected to the second driving shaft, wherein the rotational-linear transmission includes a bearing which connects to the driven shaft, and wherein the bearing applies a radial load to the driven shaft.
