摘要：

The approach used here consists of an axisymmetric gage with a tapered exterior. Raw outputs are normal stress in three directions in the plane perpendicular to the gage axis of symmetry. From these outputs, the time history of the complete state of stress in this plane can be determined. Of special interest is the plane of symmetry which is the vertical plane centered on one side of a wheeled or tracked vehicle proceeding in a straight line. The gage was placed from a berm on the side of the vehicle path, approximately 4 ft horizontally and at approximately 9 in. below the ground surface. Test vehicles were a 4 x 4 wheeled vehicle and a M113A2 armored personnel carrier. The measured stress results are largely consistent with expectations. (C) 2004 ISTVS. Published by Elsevier Ltd.
