Reducción del ruido estructural y la vibración  en un prototipo de cabina de ascensor  mediante la unión adhesiva de paneles

Authors

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.
