    摘要:

    针对箭载可回收电子设备的抗强冲击设计进行了分析研究,设备采用模块化方式方便安装和调试,采用多种措施提升设备的抗强冲击能力:对于设备和整流罩一起落地的情况,采用安装脚减振防护;对于整流罩空中解体、设备单独落地的情况,采用包角减振防护;为防止电源开关控制柄在强冲击下移位,采用开关限位凸台进行限位防护;对于印制板上的元器件,通过缓冲胶灌封来保证元器件焊点的强度,防止管脚断裂、焊点开裂;采用LED防护罩对LED雾灯提供结构防护,同时保证了LED雾灯的灯光能被观察到。结合力学仿真和力学试验,有效解决了可回收电子设备抗强冲击问题。

    Abstract:

    This paper focuses on the research on high anti-impact design of recyclable electronic equipment on rocket. The modular mode is adopted to facilitate the installation and debugging of the equipment. At the same time, many measures are adopted to improve the high anti-impact ability of the equipment: for the case that the equipment and the fairing fall to the ground together, the installation foot absorption pad is used for vibration reduction protection; for the case that the fairing disintegrates in the air and the equipment falls to the ground alone, the corner absorption pad is used for vibration reduction protection; in order to prevent the power switch control handle from shifting under strong impact, the limiting pin on power switch is used for limit; for the components on the PCB, the buffer glue is used to ensure the strength of the solder joints of the components and prevent pin fracture and solder joints cracking; the LED protective cover is used to provide structural protection for the LED lamp and ensure that the light of the LED lamp can be observed outside. Combined with mechanical simulation and mechanical test, the high anti-impact problem of recyclable electronic equipment is effectively solved.
