REDUCCIÓN DEL RUIDO ESTRUCTURAL Y LA VIBRACION EN UN PROTOTIPO DE CABINA DE ASCENSOR MEDIANTE LA UNIÓN ADHESIVA DE PANELES

Resumen

Abstract This paper presents an experimental study for the structural noise and vibration reduction in a cabin elevator by means of adhesive bonded joints of panels. For that noise and vibration measurements are carried out on two prototypes: one of them built with classical panel joining technologies and the other one with adhesive joints. First of all the mechanical properties (relaxation and complex moduli) of two low modulus materials are compared: a silane and a modified silane adhesives. These properties are obtained for both materials by means of dynamic mechanical thermal analysis technique (DMTA), the master curves under direct strain being built-up through a procedure based on the time-temperature superposition (TTS) principle. Next, the influence that these two materials have on the dynamic response of an adhesively bonded metallic beam is investigated, in order to select the right candidate according to design criteria. Finally, an application for an elevator cabin prototype is presented, in which noise and vibration are measured in order to put into evidence the benefits of joining panels by means of adhesive bonded joints in contrast to the traditional joining technologies.
