Original Abstract

The aim of the paper is to show new procedures for evaluation of measured data to the wider professional public. The paper deals with the use of the so-called Unterberger transform for dynamic analysis of two selected samples of rail fastening Vosloh W14 and Nabla. This transformation belongs to the group of quadratic, affine time-frequency methods. Part of the paper is a mathematical analysis and description of this transformation. Furthermore, the paper contains a description of the measuring method used, comparison of dynamic parameters of tested structures and recommendations for practice.
