Narrative:
After departure from sdf; climbing through 3;000ft we hit what I suspected to be wake turbulence. Immediately the airplane developed a violent vibration. When leveling off at 4;000ft the vibration became rhythmic; but slightly less violent with a pronounced oscillation. It was unusual and significant enough that both the first officer (first officer) and I felt like there was a possibility of aircraft damage and/or malfunction of some sort. We were still within a few minutes of the departure airport; so we performed an air return and precautionary landing. The first officer [flew] the aircraft on the previous leg; and confirmed that the noise/vibration was a new development. We agreed it was significant enough to warrant a return for inspection by maintenance rather than risk further damage or the creation of an emergency situation.
