ABSTRACT:
A testing device for surfaces subject to impact, comprising a transducer module and an electronics module cooperatively connected together. The transducer module includes an impact head for impact generally in the z-axis of a surface defined by an x and y-axis, and a transducer including an accelerometer aligned with the x, y and z axes for producing a voltage output proportional to the acceleration in each of the axes upon impact by the impact head on a surface. The electronics module includes a voltage source for supplying electrical energy and computer powered by the voltage source for vectorially adding the voltage output to determine the peak acceleration upon impact independent of the actual orientation of the impact head on the surface.
