Abstract

Appraise the properties of bullet synthetically, a fine instrument for measuring the equatorial rotational inertia and polar rotational inertia of various bullets and rifle grenades is precisely developed. In this measuring instrument, a double suspensions structure is adopted, and a reflecting photoelectric coupler is used to extract the signal of torsional-oscillation period of the measured bullet, the extracted signal is processed by computer, and the data concerned is output on the displayer, furthermore, the measuring precision of the instrument has been analyzed with theoretically, main factors affect the precision has been discussed. The maxima of radial deviation of the measured bullet to the ideal position and the maxima inclination of the axis of the bullet to the axis of steel wires are calculated, and measured to ensure measuring precision are proposed.
