To ensure the correctness of the spring design, through theoretical calculations to verify the availability of strength and design. The results show the strength to meet the requirements of the parts. To ensure insurance and arming of reliability，the arming reliability and recoil arming of reliability was calculated by theoretical calculation through theoretical calculations seeking a safe altitude and drop it rolled down a safe altitude，The results to ensure that the fuse 1.5 m can not be released when the fall to a sufficiently high insurance and steel rolling distance；In order to meet the extension fuze arming distance,use the static mapping to get motion parameters clockwork,and calculation of the rotor and positive time delay arming distance, the results show that the extension distance is longer than the muzzle safe distance. In order to ensure the fixed fuse after positive，the reliability of he anti-recovery mechanism action shold be calculated；In order to verify the performance of self-destruct fuze，the heoretical calculation of the state of the needle into the detonator when sideswipe depth 0.6mm shold be down , the results show that the state of sideswipe pin spring is compressed, in line with the requirements of self-destruction；To ensure the ignition performance of the fuze，the impact velocity is obtained by theoretical calculations, and then calculated the impact energy, checking ignition reliability；To ensure the rationality of size and structure design，dimensions chain of important dimension of fuze were calculated.
