Title Design for Contact Fuze of the 35 mm-caliber Automatic Grenade Launcher Triggered by Self-destruction Warhead
Abstract
Structure analysis, Intensity verification, Service processing analysis and Fuze performance analysis of the new type fuze are expounded and proved in detail, in order to meet the needs of the customers, which propose the improvement requirements of the reliability and safety. To make sure the fuze can be safe and reliable in different circumstances, and be effective when it is active, the Intensity verification of the every part of the fuze is calculated, especially where might be easy to come problems when it works in some harsh conditions. Recoil safety performance and centrifugal insurance performance are calculated by analyzing the structure and the processing of the fuze, to ensure that the function and the insurance of the fuze can work properly. Moreover, the performance of ignition mechanism is calculated and tested, and the safety of the fuze in usual condition is also estimated. The results show that the intensity of the new fuze meets the requirement, most parts of the new fuze can be mass-produced, the recoil insurance and the centrifugal insurance can work properly and the fuze can be safe in usual condition.
