METODE PENURUNAN RESPON DINAMIK SISTEM POROS-ROTOR DENGAN PEREDAM VISCOUS ROTARY
Abstract: Viscosity or
viscosity is one of the quantities that are very important in the analysis of
the behavior and movement of fluids that come into contact with other objects
such as solids {solid body). Viscous dampers can be used to reduce the
amplitude of the response due to the unbalanced mass, rotation critically,
noise and shock loads. Absorbers working with fluid film bearing securities
which are placed at a certain point, which is connected to the shaft-rotating
rotor. Certain viscosity fluid will be forced to pass through a narrow slit
with a certain pressure that can absorb the energy supplied by the shaft, this
damping effects that can provide resistance to the rotor shaft system because
the fluid has a linear damping and damping effect histeriktik. Viscous dampers
can be used to reduce vibration amplitude response at a fixed price in
accordance with the physical nature of the damper, the use of viscous dampers
are widely used to control engine speed and turbine rotational speeds are like
a helicopter rotor. From the test we can produce the damping effect on the
engine rotation can reduce the response time domain vibration with an amplitude
reduction of approximately 60% for the damping ratio ΞΆ = 0.5.
