Abstract
El presente proyecto tiene, como objetivo principal, el análisis frecuencial y
estadístico de la señal vibratoria emitida por una reductora antes y después de la
instalación de una carcasa antiruido.
Para efectuar dicho análisis se ha partido de un conjunto de ensayos
realizados sobre un banco, modelo a escala de la reductora real, en los que se
recoge la señal vibratoria emitida en diversos puntos, antes y después de la
instalación de la carcasa antiruido, a distintas velocidades de funcionamiento.
A partir de estos ensayos, la señal vibratoria se caracteriza utilizando
diversas técnicas frecuenciales y estadísticas y se realiza una colección de fichas
en las que se recoge la información sobre la que se sustenta el análisis.
Finalmente, se analizan los resultados obtenidos a partir las diferentes
técnicas aplicadas en ambos casos, antes y después de la instalación de la carcasa
antiruido.
The current project is about analyzing the vibrational signal emitted by a geared drive unit, before and after installing a noise abatement housing, using different frequency and statistics techniques. In order to accomplish the analysis, several tests have been performed using a test bench, a scale model of the real geared drive unit. The vibrational signal emitted in some spare points along de drive unit has been recorded at different working speeds and before and after the noise abatement housing installation. From that point on, the vibrational signal has been characterized using different frequency and statistics techniques and has been performed a technical specification sheets collection in which the fundamental information for the analysis is recorded. Finally, the results obtained from the different techniques applied in both cases, before and after de noise abatement housing installation, are analyzed.
