Title Systems Analysis and Design Calculations of 30mm Artillery Fuse
Abstract
Small-caliber artillery is a weapon attacks broad targets with flexible and responsive features. The problems such as redundant insurance、delaying arming 、self-destruction function、functioning at high impact angle should be taken into consideration when designing 30mm artillery fuze. In order to ensure the right structure with technology performance and make the designed element of the fuze meet the interchangeability requirements, the dimension chain concerned with the fuze should be calculated according to the extreme value method when designing. To ensure system of fuze safe and reliable, the strength-checking of the element and the security and firing performance should be analyzed and calculated. Analysis of dimension chain shows the fuze is available for engineering design. Through performance analysis and calculation, safety and reliability of the fuze are guaranteed， which conforms to the relevant requirements of GJB 373A—1997 《The Safety Criteria For Fuze Design 》.
