* (The tests were measured according the EN 826-97 at National State Laboratories ) DYNAMIC CHARACTERISTICSANTIVIBRATION HANGERSVibro - QH mini3. VIBRATION REDUCTION CHART2. LOAD - NATURAL FREQUENCY CURVES1. LOAD - DEFLECTION CURVES *For achieving optimum results in special applications, werecommend to contact our technical department for selecting thebest antivibration solution.The deflection (mm) have to be checked, for differentnumber of hangers, in combination with the assessedload (Kg) per hanger point (chart 1). Then the natural frequency, ( ) of the antivibration hangers, can be calculated (chart 2) From chart 3, with the assessed excitation frequency ofthe machine (fe = rpm / 60) and the natural frequency fromchart 2, we calculate the % theoritical vibration reduction(efficiency, n).SELECTION METHOD010203040500 1 2 3 4 5Deflection (mm)Load (Kg)90% -20dB98% -34dB70% -10dB20% -2dB101001 10 100Natural frequency fn (Hz)Excitation frequency (Hz)010203040501 10 100Natural frequency fn (Hz)Load (Kg)MKf n p2= www.vibro.gr info@vibro.gr TEOStamp
