Abstract

The vertical impact damping system with multi-degree and multi-parameter has a complicated non-linear essence. To recognize its motion characteristics deeply, the paper experimentalized on cantilever beam damper system. First the mode parameters and inspiriting residences of the experiment device were identified, and after impact force with different frequencies and amplification were imposed on the system, lots of experiment data were gained. By plotting response phase figures of the system and combining experimental phenomena which could be observed, some conclusions about the non-linear of vertical impact damping system were drawn, what would provide references for many engineers.
