Abstract


Fuze the spiral elastic seat belt mechanism is the extension of a typical arming device , can be used to rotate the shells can be used for non- rotating bomb , has a simple structure , small size , low cost , high reliability , and is not easy to lapse . In order to find a way to extend flexible seat belt mechanism arming time , the fuze the spiral elastic seat belt bodies by establishing the dynamics model , computer numerical simulation and test research methods . Arming process rotation bomb in seat belt mechanism the semicircle with bridge assumptions dynamics model based on the moment of the flexible the safety belts institutions arming process geometry analysis , analysis of the state of motion . Using MATLAB software programming based on the known parameters of each stage of the arming process numerical simulation , forecasting a the elastic seat belt arming performance . By numerical simulation of the elastic band arming performance influencing factors were analyzed , results showed that the growth seat belt length , thickness increased , reduce speed , reduce seat belt inner ring radius , increase the mandrel their constrained hole intramural friction coefficient method can effectively extend the flexible seat belt rotating bomb arming time ; while on the coefficient of friction between the insurance the width , reptiles coefficient mandrel rotation inertia , the coefficient of friction between the seat belt and the support surface , seat belt and chamber arming no impact or less impact . The application of the test apparatus of the the elastic seat belt in a non-rotating projectile , is designed for different seat belt length and the cavity radius test, and by the high-speed camera to record the testing process . The test results show that in the non-rotating shells , increase seat belt length and the radius of the cavity can extend the release time of insurance .
