Dynamic Model for Hydraulic Dissipaters
MetadataShow full item record
The paper deals with the problem of energy hydraulic dissipaters used as dissipative links for mechanical structures subjected to earthquakes, shocks and vibrations. The authors propose a mathematical model of a hydraulic link with energy dissipation, the device working reversibly to the alternative traction and compression movement. The dynamic behaviour of the energy hydraulic dissipater depends on the instantaneous frequency (speed) of the excitation generated by the earthquake, mechanical shock or vibration. The control of dissipaters is obtained by appealing at a system composed of devices for regulating pressure (energy regulators), located outside the dissipater.
