Hence, we first analyzed and studied the kinematics and dynamics of PDC bit, and that are utilized to analyzed how to hame cutters by PDC bit whirlpool. Onthe based of this, we do the cutting experiments. With the test, we not only think over the influence to force actting on cutters in rock nature, drilling parameter, cuttersdensity distributed, and also wear state of cutters and PDC bit appearance. Because the PDC bit's cutters are repeaded by polycrystalline-diamand and tungsten carbide, the specific property of PDC wear are not alike that of polycrystalline-diamand and not alike tungsten carbide.

因此，本文首先分析研究了PDC钻头的运动学和动力学，并利用分析的结果对PDC钻头的涡动是如何损坏切削齿的进行了探讨；在此基础上，进行了PDC钻头切削齿的受力实验，在受力实验研究中，不仅考虑了岩性、钻进参数、布齿密度等对切削齿受力的影响，而且考虑了切削齿不同的磨损状态、钻头的冠部形状对切削齿受力的影响；PDC钻头的切削齿是由聚晶金刚石层和碳化钨底层复合而成的，它的磨损特点既不同于金刚石的磨损又不同于碳化钨的磨损，因此，在分析了复合片磨损机理的基础上，进行了PDC钻头切削齿的磨损实验。

At present, more and more largetonnage ship is built with the development of ship industry, the forcebetween hull and slipway increased, some existent shipyard is not capableof building large ship. Besides, the damage of sh'ip structure and slipwaywere also reported. But the existed method for calculating ship launchingcan not solve it efficiently, so it is important to calculate shiplaunching precisely and take measure to preclude such accident.

目前随着船舶工业发展，建造船舶吨位越来越大，船体和船台之间的受力也随之增大，造成原有船台的设计能力有时已不能满足建造大型船舶需要，在实际生产过程中已有船体局部结构和船台不同程度损坏的报道，而现有的下水计算方法在有关船体和船台受力计算方面显得不够准确，如何准确进行计算并采取相应的措施来防止这类问题发生显得十分重要。

a。带式给煤机作为翻车机受煤斗配煤用，煤中的杂物可能造成带式给煤机的损坏，在翻车机受煤斗上部应装有篦子，翻车机翻卸完煤后，运行人员应将留在篦子上的杂物捡出，如果将杂物捅进煤斗则会造成皮带的损坏和堵煤，影响卸车。

The question of ruined earth pressure cell in test is solved,and the contact pressure between soil and pile is found out by the numerical simulation and distributing law of earth pressure.

通过数值模拟，解决试验中土压力盒损坏的问题，得到地震动激励下桩–土接触压力峰值的数据，并由此分析桩–土接触压力的大小及其分布规律，提出桩基上的支盘是基础减振的主要构件，并承受动荷载，减轻地震波对上部结构的冲击力，同时消耗上部结构反馈给基础的振动能量。承台和桩基两侧的土压力时程曲线呈反向关系，说明基础在同一时间一侧受压，另一侧受拉。
