| description | The problem of reducing the emitted vibrational energy through
pipeline systems is relevant. The paper considers the fundamental
possibility of constructing a waveguide silencer for pressure
pulsations and hydrodynamic noise using MR material (metal
rubber) with metal inclusions. The problem of evaluating the sound
insulation effectiveness and determining the locking sound waves
frequency range is posed and solved. The calculation results show
that for metal inclusions in the form of lead balls, the decrease in
the pressure pulsation amplitude is 10–20 dB in the frequency
range of about 300–1000 Hz and depends on the characteristics
of the MR material. It is shown that, if it is possible in principle,
a change in the parameters of the wave sound insulator (length,
bulk elastic modulus, mass of metal inclusions), the frequency
range for blocking sound waves can vary over a fairly wide range. |
