报告摘要:
The lecture reviews the know-why and the know-how of an invention based on the patented dissipative high-pressure force-network technology. It was found that by proper selection of damping material and hydrostatic pressure to which material is exposed during the loading one can match material maximum damping properties with the frequency or rate of the applied loading. In this way one can fully utilize energy absorption characteristics of the selected material and maximize the damping properties of a damper.
Using this unique potential of the high-pressure force-network technology, one can build ultimate damping elements that surpass the existing damping elements and sound insulation for sever orders of magnitude. Applications of such damping elements include for instance supports for industrial machines to damp vibrations, vibro-seismic isolation for buildings, vibro-seismic dampers for bridges, dampers for concrete hydraulic and electric hammer breakers, cable-bridges energy absorbing systems, and to improve passive car safety in road transportation. Finally, this technology allows building railway tracks and wagons couplers for cargo trains that could travel with velocities beyond 300 km/h.
