Measurement of Double-Strike Phenomenon of Impulsive Force Using Fluctuating Load Detection Plate

Abstract

   The fluctuating load detection plate is a force measurement sensor developed by the authors. In this study, the performance of the load detection plate is investigated by the drop tests using bowling ball and lead ball. Then, by the use of compact drop test equipment, double-strike phenomena induced by the test of weight drop to the surface of flat oil clay and by the test of weight drop to the component made from sponge rubber and cover plate are examined. Further, double-strike phenomenon is examined by the falling test of longitudinally turning bar onto round plastic stick.
