GEAR FOR DYNAMIC LOADING Russian patent published in 1998 - IPC

FIELD: formation of high-power shock waves in continuous media. SUBSTANCE: invention refers to dynamic test of construction materials. Charge of fixed chemical composition in the form of set of layers having density diminishing from point of initiation towards loaded object is used in gear for enhanced efficiency of action of charge of solid explosive by way of increase of coefficient of transfer of chemical energy to kinetic one in compliance with law , where ρ_oo is density of layer first from point of charge initiation; ρ_oi is density of i-th layer; x_i is coordinate of i-th layer; i is ordinal number of layer, i=0.1,...m, where m ≥ 3; 3; L_o is parameter of dimensionality of length; δ 0.1 and relation of density ρ_oo of first layer to that ρ_om of last one from point of initiation lies within interval 1,45 ≤ ρ_oo/ρ_om≤ 2. EFFECT: maintenance of level of applied load under diminished mass of explosive charge. 1 dwg
