Abstract

The use of a relatively new direct current (DC) electromagnetic tracking device in conjunction with a hostile metal environment of Material Testing Machine was studied. In this research, we first evaluated the reliability and performance of the DC tracking system operating in an ideal metal-free environment for both the translational and rotational error in static and dynamic conditions. When the tracking system with the same factory default configuration was moved into a heavy metal environment, serious translational and rotational distortion were observed. Through a series of evaluation of the physical environment and modification of the settings, the tracking system could perform satisfactorily and both the translational and angular error could be reduced to manufacturer's specifications. The safe working region for the DC tracking systems operating in a material testing machine environment was successfully mapped out. This study provides information for using the DC electromagnetic tracking device in the heavy metal environment exists in the material testing machine.
