Quick and dirty:
1: get a garage motion sensor and cheap extension cord. Cut the female end off the cord but leave enough wire there for splicing.
2: Open up the motion sensor and find the wires that run from the PCB board to the socket for the light bulb(s)
3: Cut those wires and wire them to the female end of the extension cord you just cut off.
4: Wire the other end of the extension cord into the wires of the motion sensor that would normally be connected directly to the electric in the house.
5: Add an unbalanced load to the drill (metal rod with weight on one side only).
6: Tape drill trigger down (or zip-tie) and plug it into the female socket you installed on the sensor.
7: Plus sensor into wall outlet.
That should give you the function of a harsh vibration. Me...I would probably use compressed air and a semi-random routine on a microcontroller or a motor with a rod attached to it that popped the drawers out with a cam-shaft style mechanism.
