涡

In the rotary scroll-pan, gyrate cover plate (8b) is erected and set on the mirror plate (8a).

在旋转涡盘，旋涡状的盖板(8b)立起设置在镜板(8a)上。

The turn speed is measured with an external hall probe and the oscilloscope, this give me a precise measurement, for instance when I insert an 6mm aluminum sheet I can see on the scope the pulse periode increased quickly, this shows that the speed of the motor drops also quickly due to the eddy currents induced in the aluminum sheet.....

转速度是衡量一个外部霍尔探头和示波器，这给我一个精确的测量，例如，当我插入一个6mm的铝板，我可以看到的范围脉搏 periode迅速上升，这表明速度电机也下降很快，由于涡电流致该铝板。。。。。。

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。
