介绍了火箭弹射座椅某型机构撞针组件功能,对故障零件进行主要尺寸检查、试打火试验,并在体视显微镜、金相显微镜下进行了观察、维氏硬度检测等理化分析,最终确定了故障形成的原因及预防措施,可有效避免此类故障现象的重复发生。
The function of the striker assembly of a certain type of mechanism of a rocket ejecting seat is introduced. The main dimensions of the failed parts are tested and the ignition test is carried out. The physical and chemical analysis such as the observation under the microscope and the metallographic microscope and the Vickers hardness testing are finally carried out The reasons for the formation of failure and preventive measures can effectively prevent the recurrence of such failures.
