连续冲击载荷条件下收音机的冲击响应特性研究与分析

Research and Analysis on Shock Response Properties of Radiogram under Repetitive Shocks

以一种典型的电子产品FH-2010型“烽火”牌收音机为对象,利用正弦振动试验、模态分析、连续冲击试验等方法研究了收音机在连续冲击载荷条件下的冲击响应,获得了冲击放大系数和冲击响应特性。这些研究方法及结果对进一步研究连续冲击载荷环境中电子产品包装结构的破损与防护理论技术有较好的参考价值。

Taking a kind of typical electronic product radiogram ＇Feng-Huo＇as research object, the shock response of the radiogram under repetitive shocks were studied by using sine vibration test, modal analysis and repetitive shocks test. The shock amplification factor and shock response properties of the radiogram were obtained. These research methods and results can be good reference for the further research works of package damage and protection on electronic product under repetitive shocks.
