design - Opis:
- The paper contemplates the provision of impact or particle dynamic vibration absorber (DVA). An efficient numerical approach based on the theoretical-experimental method is proposed to maximize the minimal damping of modes in a prescribed frequency range for general viscous tuned-mass systems. Methods of decomposition and numerical synthesis on the basis of adaptive schemes are considered. The influence of dynamic vibration absorbers and basic design elastic and damping properties is under discussion. Compact buffered impact absorbers are analysed. One task of this work is to analyse parameters identification of the dynamic vibration absorber and the basic structure. The work focused on a single degree of order (SDOF) system which is equivalent to particle DVA. The simulation provides a close agreement with the measurements over various entire frequency ranges, which means the SDOF is simple yet easy to calculate the damped motion, compared with the experimental results of particle DVA. Examples of the attachment of particle DVA’s and elongated element with multi-mass impact DVA’s are offered. The paper contemplates the provision of the impact multi-mass DVA’s with masses collisions and traction for additional damping. A technique is developed to give the optimal DVA’s for the elimination of excessive vibration in harmonic and impact loaded systems.
