包装用冲击过载指示器性能试验研究

A Study on the Performance Test of the Shock-overload Indicator for packaging

冲击过载指示器应用在包装件上,能可靠显示商品在流通过程是否经受超过脆值的冲击,便于判定野蛮装卸造成的非正常破损,为索赔提供依据,降低包装系统综合费用,具有较大应用价值。本文阐述六种不同结构原理的冲击过载指示器振动、跌落试验,评价精度、可靠性、使用寿命、有效使用频率范围以及对振动的响应,得出指示器冲击响应加速度——时间特性曲线,为自行研制性能稳定、精度可靠的包装用冲击过载指示器提供试验依据。

The shock-overload indicator is of great value to packaging. This paper introduces six types of shock-overload indicators and evaluates their accuracy,reliability,usage life,effective frequency range and response to vibration. The shock peak acceleration-shock pulse width calibration curves are developed.
