Desarrollo de dispositivos de neopreno como mecanismo de aislación de vibraciones en bases de maquinaria rotatoria industrial.

Abstract

Generally, industrial buildings require to use rotating machinery to carry out their operating processes. All machinery generates vibrations, which must be within permissible limits to ensure optimum equipment operation, prevent structural damage to the support system and that operators maintain a sense of safety in their work. These undesirable effects can appear because of the phenomenon of resonance in which large displacements occur when amplifying in an important way the vibrations in the system. This phenomenon occurs when the excitation frequency coincides with one of the natural frequencies of the system. For this reason, the implementation of neoprene devices is proposed as an insulator between the foundation and the base of the rotating machinery, in order to reduce the amplitude of vibration and the transmission of the excitation forces. This dissertation document presents the development of neoprene devices as a vibration isolation mechanism in industrial rotating machinery bases, for which a design research and calculation of the insulator’s properties was carried out. In addition, a mathematical model was developed to perform a dynamic linear analysis of the time history of the system with and without neoprene insulators, whose results were compared in order to obtain an analysis of the dynamic response of the system in resonance and the benefits of the incorporation of the insulators.
