Recently air-cushion blasting with column charge has been widely used and gained remarkable results in improvment of fragmentation and controlling damage. Based on the experimental data and theoretical analysis, this paper studies the mechanism of air-cushion and column charge in blasting and explains the reason why this charge structure is better than the traditional concentrated and conpling charge.

近年来条形药包空腔爆破的应用范围有了一定的扩展,并且在提高爆破效果和控制爆破危害等方面取得了显著效果。本文通过测试资料整理和理论分析,进一步探讨了空腔和条形在爆破中的作用机理以及为什么采用这种装药结构比常用的集中药包偶合装药爆破效果好的道理。

The cushioning performances of several kinds of packaging cushion models are analysed and the fundamental characteristics of the cushioning performances of the foamed plastics are presented based on the dynamic and static constriction experim-ents of cushions. Non-linear elastic models of two kinds of foamed plastics made inChina are constructed and the parameters of the models are fitted. The models donot only accord with the static stress-strain relation, bnt also display the fundame-ntal characteristics ef dynamic cushioning performances of foamed plastics.

Introducing the plastic strain the differential constitutive equation for viscoelastic and plastic materials is deduced from multi-integral constitutive equation for nonlinear viscoelastic materials.The dynamic cushioning performance model of expanded plastics cushions in shockproof packaging is constructed based on the differential constitutive equation for viscoelastic and plastic materials and considering the breakage character of materials.The parameters of the model of expanded polystyrene made in China are identified according to the experimental data in serial drop-type shock tests under one composite condition of drop height,cushion thickness and static stress.The comparing of dynamic calculation results with testing results expresses that the model can reflect the fundamental dynamic characters such as the variations of acceleration,velocity and displacement,the plastic deformation of cushion and so on well.The dynamic cushioning performances of the model can also fit testing results under other

本文从非线性粘弹性物质的多重积分型本构方程出发,引入塑性应变,推导了粘弹塑性物质的微分型本构方程.进一步考虑材料的损伤特性,建立了泡沫塑料包装衬垫的缓冲性能模型.根据在一种跌落高度、衬垫厚度和静态应力组合条件下的国产可发聚苯乙烯沫泡塑料的连续多次跌落冲击试验数据,识别了其缓冲性能模型参数.动力学计算与试验结果的比较表明,该模型能较好地反映可发聚苯乙烯泡沫塑料包装衬垫在连续多次跌落冲击过程中的加速度、速度、位移变化,冲击能量的吸收性和塑性变形等基本特性.并且仅根据在一种组合条件下的试验数据所识别的这一模型,在其它组合条件下其缓冲性能与试验结果也吻合较好.
