Abstract: An instrument for measuring the rotational inertia of various Dullets and rifle grenades with precision is introduced. In this measuring instrument, a double suspension structure is adopted, and an optoelectronic timing system is used to extract the information of the periods of torsional-oscillation of the measured bullet. The data is processed by the measuring system consisting of MCS-51 series of monolithic computers, and the measured results are displayed on displayer LED. In this paper, the working principle of the instrument is expounded, the relevant formulae are derived, and the main factors affecting precision discussed. Precision of the instrument is analysed quantitatively. Experimental results and measuring precision are given.
