Abstract: A shock testing apparatus includes a tower extending upward from a base. The tower includes a guide extending down the tower. A strike plate assembly includes a strike plate positioned below the guide for receiving mechanical shock from a striker striking out from the guide. A tri-axial accelerometer is mounted to the strike plate for data acquisition of three-dimensional shock wave acceleration data. A method of mechanical shock testing components includes dropping a striker onto a strike plate on which is mounted a unit under test (UUT) to generate three-dimensional shock waves through the strike plate. The method includes acquiring data indicative of acceleration in three orthogonal directions in at least one of the strike plate or UUT for a single drop of the striker.
