Passive gas-liquid oscillation dampers are often used
to change the settings and dynamic
properties of a hydrodynamic stand. If changing the degree of influence on the dynamic
properties of the system
is necessary, the possibility of damper regulation should be en-
sured such as a change in the gas volume or mass of the moving elements. To account for
these changes simplified mathematical model of the gas-liquid oscillation damper, as a
lumped parameter system, is proposed.
Keywords:
mathematical model, hydrodynamic stand, gas-liquid oscillation damper.
