Abstract
This paper demonstrates the unsuitability of relations and diagrams known from literature for antiresonant machines, in terms of determining the position of resonances of dynamic elimination systems. Correct formulas were derived and a nomogram for designers was built based on them. The effect of the actual number of degrees of freedom on the natural frequencies of machines with a design based on the dynam-ic eliminator principle is presented. The effect of the spring mass on the antiresonance frequency explicit to the natural frequency of the eliminator was pointed out, and correct relations for its consideration were derived. The experimental and numerical studies carried out in this paper have confirmed that including the effect of spring inertia in analytical calculations improves the accuracy of the results obtained. Furthermore, it was shown that the actual way in which the ends of the leaf springs are attached can significantly affect the natural frequency of the system. The factors discussed and analysed in this paper are omitted in conventional vibrating machine calculations, resulting in an overestimation of the natural frequencies determined from them.
