Abstract : a previously proposed approximate quasi - static theoretical method is employed herein to examine the deformation and perforation of a simply - supported circular plate struck by a flat - faced projectile at normal incidence. based on the principle of virtual work, static load - displacement relationships are first obtained and then used to predict the energy - absorbing capacity of the plate subjected to relatively low speed impact. it is shown that good agreement is obtained between the theoretical predictions and the available experimental data, provided that adiabatic shear plugging failure does not occur, but the influence of strain rate sensitivity is taken into account
文摘:採用準靜態近似理論方法分析簡支圓板在平頭彈丸正撞下的變形和穿透.首先基於虛功原理得到了靜態荷載位移關系,並將其用於預測低速沖擊下圓板的能量吸收能力.當考慮了材料的應變率敏感性,並且不發生絕熱剪切沖塞破壞的前提下,理論預測和實驗結果吻合良好According to calculation, synchronous closing can reduce the value of over - current and over - voltage in the closing transient process. the closing of capacitor is taken as an example to analyze movement process of synchronous closing. it also analyzes the impact of pre - strike characteristic, environmental temperature and control voltage on synchronous closing
