Hi Kandavelan,
There would be the Jiggle Deformer, or if you like to have more control the Pose Morph*.
Other ways could be, but not certain if that is as good as the options above, that you animate one cycle and use a perhaps a Point Cache with a Point Cache Deformer (Use Falloff e.g, Spherical here).
*Sometimes a connection via XPresso might be an idea, but I guess a more natural, than logical connection is wanted.
All the best
