The shake table consists of a flywheel, a camshaft, a vibration table and user designed cams. The cam is connected to a variable speed dc motor with the help of a camshaft. A circular mounting plate is based on the vibrating plate through a T-slot, so that, the test structure can be mounted at any desired angle relative to the angle of incidence of the base motion. The flywheel assembly ensures frequency control with less than 3% accuracy. A set of four cams have been produced to generate harmonic motions of different amplitudes and, also, to provide saw-tooth type of base motions. By varying the speed of the motor, the frequency content of the base motion can be varied..
