ABSTRACT:
The tuft impact tester mounts a test probe in a suspended manner from a tripod arrangement via a gimbals mechanism so that the test probe is able to move along a vertical axis. The test probe is dropped from a predetermined height, the velocity of the test probe is measured prior to impact on a ground surface and the deceleration of the test probe caused by the ground surface is measured. The two values are used to determine the relative hardness of the ground surface.
