machine F() т isolator fundation
A textile machine with a mass of 5000 kg must be isolated from transmitting force to the
foundation. A spring can be used as an isolator between the machine and the foundation.
The forcing function can be expressed as
F(t) = 100 sin(ωt) + 5 sin(2ωt)
where the force is in Newtons, t is in seconds, and frequency ω = 1200 rpm. Commercial
isolators (springs) are available from the machine manufacturer. These isolators are rated by
their deflection under the weight of the machine and are available in ratings of 6 and 8 mm.
(a) Determine the steady state responses of the machine for the two springs, respectively.
(b) Of the two springs, which one provides better isolation from transmitting force to the
foundation?
