Today represents vibration analysis an inseparable part of the product design, especially aeronautical components, machine tools etc. One of the vibration analysis methods is the so-called modal analysis, which determines the modal parameters of the researched structure. This paper deals with a comparison of two commonly used approaches, namely „Single Input Multiple Output“ (SIMO) and „Multiple Input Multiple Output“ analysis (MIMO). A MIMO procedure of measurement is developed and discussed. Both analyses are executed by the same conditions on the milling machine based on parallel kinematics in order to objective comparison. The results show that the choice of the so-called reference points is very important. In case both references are appropriately selected, the MIMO analysis gives better results that the SIMO one.
