Amplitude Frequency Response Characteristics of Fe-based Damping Alloy Simple Beams under Forced Vibrations

摘要：

The amplitude frequency response characteristics of simple beams made by Fe-Mn damping alloy, Fe-Cr-Mo damping alloy and 0.45C-steel under forced vibrations were studied using forced vibration measurement instrument. The results indicated that at forced vibration condition, the damping behaviors of Fe-Mn and Fe-Cr-Mo alloy beams were that the resonance amplitude and the resonance frequency range were reduced. The higher the exciting force was, the better the damping capacity of Fe-Mn alloy beam was, so it was suitable for the environment where higher vibrating force and shock existed. Whatever the exciting force was high or low, the damping capacity of Fe-Cr-Mo alloy beam was higher than 0.45C-steel, so it was more suitable for the environment where the strain amplitude changed in a wide range.
