Abstract

PURPOSE:To obtain a small-sized, high-precision impact value measuring instrument by transducing impulsive force into charge and then measuring it. CONSTITUTION:When an impact value measuring instrument 1 is fitted to a body to be measured and the both is dropped, impulsive force applied to the body to be measured expands and contracts springs 3 and 4 and a weight 2 moves in a direction. A, allowing a contact surface 2b1 to collide against the electrode surface 5b1 of a piezoelectric element 5. In this case, charge Q which corresponds to the impulsive force G is generated at the piezoelectric element 5. This charge Q is accumulated in a capacitor 7 through a diode 6. After a test, a voltmeter measures a voltage between both output terminals 8 and 9 of the capacitor 7 to find the impulsive force G.
