合成应力爆破模型hybrid stress blasting model
合成应力爆破模型在长时间内具有具体描述爆破过程的潜力、但目前只应用在研究中In the long term, a hybrid stress blasting model has the potential to provide a practical description of the blasting process but is currently limited to research applications
因为缺乏成熟的机械破碎模型、爆破行业只好依赖经验方法The blasting industry has had to rely on empirical approaches in the absence of a proven mechanistic fragmentation model
无模爆炸成型基本原理有模爆炸成型主要依靠模具来控制零件的形状和尺寸。无模爆炸成型是金属板料在动载作用下造成各质点间的相对运动来实现的basic principle of modeless explosive forming
球形容器无模成型过程球形容器无模爆炸成型是在预制的球内接多节锥台壳体中充满水,在球心处引爆球形炸药包,依靠爆炸冲击载荷的可调节性来控制爆炸冲击载荷与壳体变形阻力之间的矢量差,造成壳体各质点之间的速度矢量差,推动壳体板料按预定方向变形。在变形过程中,爆炸冲击载荷的动能转变为变形能,使各质点的运动速度重新分布,并使多节锥台壳体趋向为球形modelless explosive forming process of spheric containers
由于岩石破碎不理想、影响到开采计划的实施、进而影响到开采成本、常用的爆破破碎模型只能对破碎曲线进行粗略分析Current blast fragmentation models tend to focus on the coarse end of the fragmentation curve because of the impact of poor fragmentation on excavation performance, and hence excavation costs
金属爆炸成型模型律在各类金属爆炸加工中,对于大型零件的爆炸成型,往往因材料昂贵,模具加工周期长,操作困难,工艺参数不能准确确定而不能直接采用大型件进行试验,只能采用模拟的小型件来探索真实零件加工时的工艺参数和工艺条件。这种方法便称为模型律model simulation of metal explosive forming
