本文介绍青岛钟仪二厂自行设计制造的FSM-4数字石英计时仪强冲击试验概况、结果分析、国产C-200型冲击机与美国海军轻量级冲击机冲击谱特性比较以及冲击响应谱理论计算概要。强冲击试验是按照美军现行规范MIL-S-901C(海军)要求,采用C-200型冲击机(图1)进行。计时仪内装置了高精度石英振荡器,易碎杜瓦保温瓶和玻璃壳荧光数码管以及集成电路。而且,除石英振荡器和杜瓦保温瓶外,电子元器件的布置、结构安装:均未作特殊的防冲处理。所以,它的强冲击性能试验及其良好效果,对于舰船用电子设备的防冲试验、抗冲击设计和研究、有一定的参考价值。
In this paper, Qingdao Bell Instrument Factory Design and manufacture of FSM-4 digital quartz chronograph strong impact test overview, the results of analysis, domestic C-200 impact aircraft and the United States Navy impact characteristics of light impact spectrum and shock response spectrum theory Calculation summary. The impact test is based on the current US military requirements MIL-S-901C (Navy), using C-200 impact machine (Figure 1). Chronograph equipped with high-precision quartz oscillator, fragile Dewar thermos glass and glass fluorescent tubes and integrated circuits. Moreover, in addition to quartz oscillator and Dewar thermos flask, the layout of electronic components, structural installation: None of the special anti-puncture treatment. Therefore, its strong impact performance test and its good effect, for shipboard electronic equipment anti-impact test, impact design and research, have some reference value.
