爆炸模型的参数化建模方法

针对爆炸模型常规参数化建模存在的问题,提出一种新的建模方法.以常见的炸药—传播介质—结构模型为例,论述常规的建模方式及其在参数化建模时的局限性,提出一种新的建模和划网格方式以适应参数化建模,给出炸药和井筒位于不同位置时的计算结果.模拟结果证明:该方法能解决当炸药和井壁的投影相交时难以参数化建模的问题,具有更强的灵活性和适用性,可为从事爆炸研究的工程人员提供指导.

Parametric Modeling Method of Explosion Model

Aiming at the problems existing in conventional parametric modeling of explosion model, a new modeling method is proposed. Taking the common explosive-propagation media and structure model as an example, the conventional modeling methods and their limitations are discussed. A new modeling and meshing method are proposed to adapt to parametric modeling. The calculation results are given when explosives and wellbore are located at different locations. The simulation results show that the proposed method can solve the problem that it is difficult to parameteric modeling when the projection of explosive and well intersect. The new parametric modeling method has stronger flexibility and applicability, which can provide guidance for engineers in explosion research.
