查询词典 cone

In designing process, it will waste time on determining parting directions. For this reason, we generate a method for checking partibility by using the relations of the normal vectors of shapes. If the mold was decided as partible object, the process would evaluating the range of the parting directions. Also, the result of parting directions will be demostrated by one cone named parting cone. The total procedures of determining partibililty require O time.

基於这样的原因，本文提出一个判断可脱模性的方法，利用自由曲面上三角化之后所得到的法向量的分布情形，进行运算，若判断为可脱模模型，并计算出可脱模模型的脱模范围，使用圆锥表示之，此圆锥既称为脱模角，过程所需的时间复杂度为O；若判断为不可脱模模型则所需要的时间复杂度为O。

The explosively formed projectile with fins for a cover charge structure by LS-DYNA software which four covers were conglutinated on the liner was studied by three-dimensional numerical simulation. The mechanism of forming EFP with fins was discussed based on the curves of velocity and pressure vs time of the liners. A contrastive analysis was carried out on the three kinds of liners which include big-cone shaped liner, imperfect-sphere shaped liner and arc-cone shaped liner.

采用LS-DYNA对在药型罩上粘附隔板结构形成带尾翼型爆炸成型弹丸(explosively formed projectile，EFP)进行三维数值模拟，从药型罩微元压跨速度和压力的角度初步探讨了形成尾翼型EFP的机理，对同一直径的大锥角型、球缺型和弧锥结合型药型罩形成的尾翼型EFP进行了对比分析，三种结构药型罩均能形成较为明显的尾翼，其中大锥角型药型罩得到的EFP速度最高。
