This paper describes the preliminary impulse mode operation of a three dimensional shaker. Most of the shakers used for the accelerometer calibration are designed to be operated under the one dimensional mode. However, it is almost a taboo to ask about the cross motion or locking motion of these shakers. In order to meet the high precision calibration requirement, we have started developing the control method for three dimensional shaker using feedback control and precise measurement. Control is of paramount importance to enhance the purity of impusive motion of a shaker. Calibration of accelerometers using an impact acceleration with mili second order duration time is indispensable in automobile industries. The impact acceleration generation using a shaker is also important from the view point of traceability.
