Abstract:In plane dynamic loading experiments, the velocity of flyer and state of impact are key parameters of loading condition. A technique of electric pins for measuring the above parameters is designed, aiming at deducing a real velocity of flyer and slant of impact from local records of pins signs through a certain arrangement of the pins. The method has been used in experiments of shock activating Si 3Ni 4 powder materials, and the results are satisfactory.
Keywords:velocity measurement  electric pin technique  plane dynamic loading  impact slant
