“…There even exist a few cases, where some specific operating points of a machine result in a structural instability, which may end up in the worst case of a destruction of the plant. As a counter measure against such unwanted resonance effects so-called vibration absorbers are widely used, which basically represent an oscillating system acting against the resonance of a vibrating primary system or structure, see for instance [1,2,3,4,5,6]. Most vibration absorbers are able to operate at a single frequency and, thus, are designed for one specific working point.…”

Unwanted resonances in industrial plants often result in unpleasant noise or may even end up in a reduced lifetime of mechanical structures and components. Such vibrations are often reduced by wellestablished vibration absorbers, which are designed and precisely tuned to one specific frequency. Furthermore, often the natural frequency of, for instance, a mechanical structure is not accurately known and must be identified by an experimental modal analysis. Another limitation of conventional single-frequency absorbers is that in some applications the frequency of the unwanted vibrations varies over lifetime, which reduces the effectiveness of the initially designed absorber. Moreover, in many cases the frequency of the undesirable vibration changes with the operating point of the plant, which requires the installation of multiple vibration absorbers with different operating frequencies. In this paper a new hydro-mechanical vibration absorber with a continuously adjustable operating frequency is presented, which eliminates the shortcomings mentioned above. In contrast to conventional absorbers the stiffness of the hydro-mechanical spring mass absorber is realized by a gas-loaded hydraulic capacitance, which depends on the mean operating pressure. The concept of the presented absorber is investigated theoretically and validated by simulation experiments. The results are discussed in detail and an outlook on further steps in development is provided.

The multilevel buildings are vulnerable to the excitation forces such as winds and earthquakes. The analysis of vibration reduction in multilevel building is established in this study. The experimental and simulation method are conducted in laboratory scale. The multilevel structure model is design to be two-floor building model. The Tuned Liquid Column Damper (TLCD) is placed on first-floor of the building model and then it is placed on second-floor of the building model. The TLCD’s mass ratio and its orifice cross-sectional area are varied. The experimental results correspond well to the simulation results. The TLCD’s mass ratio does not provide significant difference, while the variation of orifice cross-sectional area provides significant differences.
