Narrative:

Mins after takeoff, during climb, there was a noticeable tremble under my feet at floor. This was felt by all flight attendants, more so in the tail end. It continued and became more noticeable. Flight attendant called captain to report the unusual vibrations. Captain and first officer had already noticed something was not right. Decision was made to declare emergency and return to jfk. We were not to prepare for evacuate/evacuation. We landed at jfk without incident and aircraft was taken OTS. We got a different A300 and resumed sequence. Supplemental information from acn 570828: felt and heard a strong vibration by the door, ceiling, floor, and galley in the aft.
