一种纸浆模塑包装制品的动态缓冲特性分析

Dynamic Cushioning Analysis on a Kind of Moulded Pulp Structure

针对用于电子枪包装的纸浆模塑包装制品进行了跌落冲击实验,分析了该包装制品在4种跌落高度下的动态缓冲特性,获得了这种包装结构的峰值加速度-静应力曲线,并利用多项式曲线拟合法和最小二乘法推算出曲线的经验公式及其特征系数。

Dynamic cushioning property of a kind of moulded pulp packaging structure was investigated by a series of drop shock tests at four drop heights,the peak acceleration and static stress curves of the moulded pulp structure were obtained,their experiential formulas and characteristic factors of these curves were derived by using polynomial curve fitting and the least square method.
