It is proposed to apply a composite sheet of viscoelastic material encapsulated in ABS plastic to be used in the design of a prototype of vibration isolator in the use of motor bases. The cyclical impact tests presented are carried out with an insulator unit named as a viscoelastic sheet that takes advantage of Hooke's law 3D. Using a vibrating equipment, reproductions of impacts are made to study the ability of the vibration isolator to resist impacts and evaluate its useful life. Through the analysis of force and variation in the response to its natural frequency of vibration, the evaluations and its behavior to the tests are established, and its change to a passive type of isolator. The evolution of the damage in the viscoelastic and the appearance of cracks is also shown.
The purpose of this research is to develop a vibration isolator using auxetic viscoelastic sheet technology. The procedure for the design and elaboration of the insulator using polymers and by means of fatigue analysis using impacts is exposed, the absorption of energy by cycles is compared and the damage that is produced in the viscoelastic is observed with an optical microscope. This is to compare the variation in the force that the fatigue equipment exerts to deform the sheet in the same magnitude and to be able to establish, through the ratio of absorbed energy and returned energy, criteria on the useful life of the element for future designs.
