Narrative:
In the landing roll below 80 KTS the nose wheel started vibrating; below 60 KTS the aircraft was vibrating excessively until about 20 KTS. The nose wheel vibration at 4 KTS was bad enough that you could hear it slamming against itself giving considerable concern for structural integrity of the landing gear system. Upon reaching the gate I advised maintenance of my concerns and there first response was would I ferry it? I stated that I would not. I had just advised them of an aircraft that had a nose gear problem that resulted in violent vibrations at 4 KTS and they wanted to reposition the aircraft. After that they called a deadheading captain and convinced him to take the flight. Had it not be for the first officer stating that he would not fly the plane in that condition the company would have repositioned this plane. The company did not tell the captain that this event had occurred 10 other times since august. I do not know why the nose wheel was shaking violently; that is beyond my expertise. I do believe that the greatest concern of the company was to get the plane back in revenue service; it was not safety.
