Modelling of the vibration exposure in typical working machines by means of random input signals

The aim of the paper is to formulate a generalized methodology of modelling random vibrations that are experienced by machine operators during their work. In the following paper, spectral characteristics of input vibrations are specified in such a way that the generated excitation signals are representative for different types of working machines. These signals could be used for determination and evaluation of risks from exposure to whole-body vibration.
