Title Design for a bullet fuze of shrapnel supplied for a new kind of cannel howitzer
Abstract
This fuze is applied to a bullet of sharpnel supplied for a new kind of cannel howitzer. The fuze has detonator safety, safety redundancy, delay bursting according to setting, sterilization, self-destruction. Since the cannel howitzer is different from the traditional howitzer that it has only two bullet,this fuze is quite different from traditional ones. In order to get a better design, analyse Sweden 155mm shrapnel, and the development of our country’s. flame-proof insurance is a sliding block.The explosion sequence is Dislocation. Delay detonator control the delay time. Draw up the fuze’s design drawing including general drawing, parts drawing, dimension chain drawing. Check the reliability of the fuze by strength calculation, including storage reliability, lunching reliability and working reliability. According to dimension chain calculation ,make sure that every part can be assembled correctl. General analysis and calculation show that the fuze can timing correctly and work reliably. The fuze safety satisfies the relevant request of “Fuze Design, Safety Criteria for”and“Fuze environment and performance test methods”.
