Question

A small reciprocating machine weighs 50 kg and runs at a constant speed of 6000 rpm After it was installed, it was found that the forcing frequency is too close to the natural frequency of the system. What dynamic vibration absorber should be added if the nearest natural frequency of the system should be at least 20% from the impressed frequency

Step 1

To convert this to Hz, we divide by 60 (since there are 60 seconds in a minute) and then multiply by 2π (since there are 2π radians in a cycle). So the impressed frequency is: Impressed frequency = (6000 rpm / 60) * 2π = 628.32 Hz Show more…
