Study On Dynamic Characteristic For Fuze Under Detonation Field Environment

The working of following fuze of tandem warhead must suffer the detonation field environment of precursory warhead, which has very important signification on the design of the following fuze.Begain from study on detonation translation mechanism in this paper, the equivalent model has been established on contact explosion of following bullent and precursory warhead,the explosive loading feature has been studied on the following bullent and following fuze through the method of go around on shock wave; The scheme of the following fuze has been designed, the dynamic feature and stress wave translation feature has been studied in explosive shock condition. The dynamic test method has been sdudied for the following fuze lastly, advanced that simulates explosive loading with Harmer, and tests the dynamic feature of fuze with the method of rocket car full flow simulation dynamic.The main study content and fruit as follows:1. The explosive shock loading’s value has been calculated through building equivalent explosive model on precursory warhead and following bullent by the method of go around on shock wave. The result accords with Autodyn’s simulation results.2. The time of inertia armer arming has been calculated under explosive shock loading, and theoretical has been proved for which’ the method of arming using detonation field environment". The dynamic translation feature of stress in fuze has been analysed and the measure of improving resisted over high loading has been advanced.3 The loading model of Harmer has been builded, and the result accords with the value which tested by copper cylinder press sensor, and advanced that simulates explosive loading with Harmer. Desighed rocket car full flow simulation dynamic test method for following fuze.
