与impact bit相关的网络例句 [注：此内容来源于网络，仅供参考]

A model of the impact between the bit and the wall of well is set up. The impact is simplified as an impact of two cylinders. According to the coefficient of restitution obtained from experiment and the speed of the bit before impact, the speed of the bit after impact and the impacting force can be worked out.

通过建立钻头与井壁的碰撞模型，将碰撞简化为两个圆柱筒之间的碰撞，利用冲量定理和实验方法获得的钻头与井壁碰撞时的恢复系数及钻头碰撞前的速度，可计算出钻头与岩石碰撞后的速度和碰撞时产生的碰撞力。

In order to analyzes the soil deformation mechanism under the impact load of the step-bit, the finite element model of impact and displacement drilling with down the hole hammer is established on the basis of adopting Drucker-Pager yield criterion, taking soil as DP materials and simulating the drilling process by applying the impact load on soils.

为了分析阶梯钻头冲击挤密作用下土体的变形机理，将土体视为DP材料，服从Drucker-Prager屈服准则，通过钻具与土体之间的接触以及施加冲击载荷来模拟钻进过程，建立了潜孔锤冲击挤密钻进的有限元模型。

In order to raise drilling speed of the non saline dome wells in Kenkiyak Oilfield, the relationship between rake angles of the cutter, profile of the bit, which have effect on cutting depth and impact-resistant of PDC bit cutters, and cutting efficiency is studied respectively using finite element analysis according to rock properties of the research area. The structure of the PDC bit is then optimized by using the research result.

为提高肯吉亚克油田非盐丘井钻井速度，根据地层岩石力学参数评价结果，利用有限元方法对影响PDC钻头攻击性和抗冲击性的齿前角、冠部形状等结构参数与破岩效果之间的关系进行了研究，并对PDC钻头的结构进行了优化设计。
