In current antivibration packaging designs, transport vibrations are generally assumed to be Gaussian random vibrations, and the cushioning material is designed so that the acceleration root mean square (RMS) transmitted to a product is low. However, transport vibrations are often non‐Gaussian random vibrations, and therefore, it is necessary to carry out antivibration packaging design, taking into consideration the non‐Gaussianity characteristics and acceleration RMS of the transport vibrations. In this study, a kurtosis response spectrum was proposed, which is an antivibration packaging design index, taking into account the non‐Gaussianity of transport vibrations. A kurtosis response spectrum is a plot of the kurtosis of the acceleration response for a series of single degree of freedom (SDOF) systems to the base acceleration input, assuming that the packaged product is the SDOF system. The kurtosis response spectrum was applied to the actual transportation data, and the results confirmed that the kurtosis of product response acceleration is different, depending on the natural frequency of the packaged product. Experiments were conducted using a dummy packaged product, and the experimental results showed good agreement with those of the kurtosis response spectrum analysis. It can be concluded that the kurtosis response spectrum is useful to clarify the effect of natural frequency on the kurtosis response. By referring to the kurtosis response spectrum, packaging engineers can obtain the necessary information to perform antivibration packaging design, taking into account the non‐Gaussianity of transport vibrations.

考虑峰度的抗振包装设计峰度响应谱分析的开发和验证

在当前的防振包装设计中,通常将运输振动假定为高斯随机振动,并且将缓冲材料设计为使得传递到产品的加速度均方根(RMS)低。但是,运输振动通常是非高斯随机振动,因此,有必要进行防振包装设计时要考虑运输振动的非高斯性和加速度RMS。在这项研究中,考虑到运输振动的非高斯性,提出了峰度响应谱,这是一个抗振包装设计指标。峰度响应谱是一系列单自由度(SDOF)系统对基本加速度输入的加速度响应的峰度图,假设包装的产品是SDOF系统。峰度响应谱应用于实际运输数据,结果证实了产品响应加速度的峰度有所不同,具体取决于包装产品的固有频率。使用虚拟包装产品进行实验,实验结果与峰度响应光谱分析的结果吻合良好。可以得出结论,峰度响应谱有助于阐明自然频率对峰度响应的影响。通过参考峰度响应谱,包装工程师可以在考虑运输振动的非高斯性的情况下获得执行防振包装设计所需的信息。峰度响应谱应用于实际运输数据,结果证实了产品响应加速度的峰度有所不同,具体取决于包装产品的固有频率。使用虚拟包装产品进行实验,实验结果与峰度响应光谱分析的结果吻合良好。可以得出结论,峰度响应谱有助于阐明自然频率对峰度响应的影响。通过参考峰度响应谱,包装工程师可以在考虑运输振动的非高斯性的情况下获得执行防振包装设计所需的信息。将峰度响应谱应用于实际运输数据,结果证实了产品响应加速度的峰度有所不同,具体取决于包装产品的固有频率。使用虚拟包装产品进行实验,实验结果与峰度响应光谱分析的结果吻合良好。可以得出结论,峰度响应谱有助于阐明自然频率对峰度响应的影响。通过参考峰度响应谱,包装工程师可以在考虑运输振动的非高斯性的情况下获得执行防振包装设计所需的信息。结果证实,根据包装产品的固有频率,产品响应加速的峰度有所不同。使用虚拟包装产品进行实验,实验结果与峰度响应光谱分析的结果吻合良好。可以得出结论,峰度响应谱有助于阐明自然频率对峰度响应的影响。通过参考峰度响应谱,包装工程师可以在考虑运输振动的非高斯性的情况下获得执行防振包装设计所需的信息。结果证实,根据包装产品的固有频率,产品响应加速的峰度有所不同。使用虚拟包装产品进行实验,实验结果与峰度响应光谱分析的结果吻合良好。可以得出结论,峰度响应谱有助于阐明自然频率对峰度响应的影响。通过参考峰度响应谱,包装工程师可以在考虑运输振动的非高斯性的情况下获得执行防振包装设计所需的信息。实验结果与峰度反应谱分析结果吻合良好。可以得出结论,峰度响应谱有助于阐明自然频率对峰度响应的影响。通过参考峰度响应谱,包装工程师可以在考虑运输振动的非高斯性的情况下获得执行防振包装设计所需的信息。实验结果与峰度反应谱分析结果吻合良好。可以得出结论,峰度响应谱有助于阐明自然频率对峰度响应的影响。通过参考峰度响应谱,包装工程师可以在考虑运输振动的非高斯性的情况下获得执行防振包装设计所需的信息。
