Abstract
Following UNE 10848:2007 speci¯cations, the vibration reduction index of croos-joints can be measured in laboratory. Due to its recent publication and the high cost of facilities and equipment there are not yet, in Spain, available laboratories offering such measurement. Numerical calculation is a clear alternative to the measurement, allowing saving cost and time, although an experimental validation is needed to provide reliable data. This communication presents a numerical model for the calculation of Kij. The results are compared against measurements in a scale model of the facilities described by the norm.
