摘要

摘要: 应用ANSYS/LS-DYNA模拟粒子冲击破岩的三维非线性冲击动力学问题，得到了破岩过程中能量的转化关系以及粒子冲击破岩的演化过程，分析了粒子冲击破岩机理。模拟结果较好地反映了粒子冲击破岩的物理过程，模拟结果与实验结果基本一致，证明了模拟方法的可行性。研究结果为水力参数优选等提供一定的理论依据。

Abstract: The three-dimensional nonlinear dynamics of particle impacting breaking rock is simulated with LS-DYNA3D. The energy conversion curves and the process of rock breaking under steel particle are obtained, and the mechanism of rock breaking is also analyzed. The simulation results agree with the experimental observations basically. Therefore, this simulation is feasible and can be used as a good reference for optimizing hydraulic parameter for oil well drilling.
