An air compressor of mass m1 = 150 kg is mounted on a spring of stiffness k1= 3000 N/m. The measured
displacement amplitude X1 = 0.0002 m at the operating speed of N = 1800 r/min. If an undamped isolation
system with mass m2=12 kg and a natural frequency w2 = 105 rad/s is fixed to the compressor, calculate the
changed displacement amplitude X1 for the overall system
As far as I understand this is the relevant equation: X1/delta_st=(1-(omega/omega2)^2)/((1+k2/k1-(omega/omega_1)^2)(1-(omega/omega_2)^2)-k2/k1)
The Attempt at a Solution
As far as I understand its a vibration absorber problem.
I dont think thats right :|
