When carrying out a vibration analysis of a composite system, the point is mainly determining stiffness and attenuation between individual elements. The TVS method deals with this analysis in case that the elements are arranged linearly and oscillations predominate in one direction only.
The frequency region analyzed by this system is between 5 and 180 Hz. The system consists of one vibrator, one strain gauge, and twenty accelerometers which are attached by means of double-sided adhesive tape to the analyzed structure.
In this structural arrangement, also the precise location of the sensors and the actual values of the variable properties of the measured system make a difference to a certain extent. The content of this article is the verification of the TVS method for two basic methodology requirements, repeatability for an identical sample and resolution for two different samples, i.e. we determine the extent to which minor variations of the state of the measured system and small variations in the position of the sensor locations influence the results obtained using the TVS method.
