触/延手榴弹引信开闭功能测试方法研究
Research on Test Method of Open⁃Close Function of Trigger/Delay Grenade Fuze
针对性能鉴定试验需要考核测试触/延手榴弹引信第一碰撞信号的时阈和开闭灵敏度的问题, 通过研制测试设备以及设计试验方案, 实现了对触/延手榴弹引信开闭功能的考核评估。通过分析触/延引信的结构组成和作用机理, 确定了引信中碰炸开关可靠闭合的临界条件, 结合产品性能指标规定的时阈要求, 提出了基于PLC程序控制手榴弹保险握片松开至跌落中硬地面全流程精准管控的设备研制方案, 确保了手榴弹的跌落高度和与中硬地面的碰撞时间, 有效解决了触/延引信开闭时阈和开闭灵敏度无法考核测试的技术难题。
Aiming at the problem that the time threshold and open-close sensitivity of the first impact signal of trigger/delay grenade fuze need to be examined and detected in qualification test, the open-close function of trigger/delay grenade fuze was evaluated by developing test equipment and designing test scheme. By analyzing the structure and principle of the trigger/delay fuze, the critical condition for the reliable closure of the crash switch in the fuze was determined. Combining with the time threshold requirements stipulated by the product performance index, a device development scheme based on PLC program to control the accurate control of the whole process from opening the grenade safety grip to falling to the concrete floor was proposed, which ensures the fall height of the grenade and the collision time of the concrete floor, and effectively solve the technical problem that the open-close time threshold and the open-close sensitivity of the trigger/delay fuze could not be tested.
