Executive Summary Core judgment: For a 55 kW screw air compressor running at 2,950 r/min, shear-type rubber isolators with a natural frequency of about 8 Hz yield a frequency ratio r ≈ 6.2, a theoretical transmissibility of about 2.7%, and an isolation efficiency of about 97.3%. Because the ...

Executive Summary Core judgment: For pumps running at 2,900 r/min, shear-type or spring–rubber composite rubber isolators are a viable and economical choice. Controlling selection with a frequency ratio r = f/f0 ≥ 2.5 and targeting r ≈ 5 brings theoretical transmissibility down to about 4% and ...
