查询词典 cutterhead

Cutterhead is one of the most critical components of shield machine.

刀盘是盾构机中极其重要的部件，本文介绍了盾构机刀盘液压控制的驱动系统、密封系统及自动润滑系统的工作原理及其维护方法。

Theoretical equations by analyzing earth pressure balance shield cutterhead′s cutting the ground are deduced and the numerical model is set up.

通过对土压平衡盾构掘进机刀盘切削土体进行理论分析，建立数学模型，得出相应计算公式。

Universal cutterhead is often used in machining expecially in machining chamfer where vaarious working positions of main axis suitable for different needs of machining various details can be obtained by rotating horizontal and oblique axes of universal cutterhead .

万能铣床在机械加工的过程中经常用到，特别在加工斜面的时候，可以通过万能铣头的水平轴和斜轴的旋转来获得各种不同的主轴工作位置，以适应加工中各种零件的不同要求。

At the request of Western Cutterhead's Ken Anselm, Troyke designed and built a 10-inch diameter table that would have the above 6-inch prototype's geometry and rigidness while using less of the machine's X and Z axis envelope.

应西方的Cutterhead的肯·安塞尔姆的要求，Troyke 设计并且建造将有上述6英寸的原型的几何学和rigidness的一张10英寸的直径桌子，使用较少机器的X和Z轴信封。

The interaction between cutterhead of shield machine and soils was simulated. The investigation shows that there exists a wider range from active pressure to passive pressure for supporting face stability.

研究表明，仅从保证地表既不隆起又不沉陷的约束条件考虑，掘进工作面从主动土压力到被动土压力存在较大的范围。

The realistic face pressure is expected to be equal to earth pressure at-rest both for making face stability and decreasing fraction resistance between cutterhead of shield and soils during tunneling process.

考虑到减少刀具磨损和节约能源问题，推荐理想的掘进工作面土压力为静止侧向土压力。

Compared with the field measurements, the formula is suitable for the distance within the shield cutterhead (±2L), which can help guiding actual tunnel construction.

通过实例计算并与实测结果对比发现，使用盾构变形计算公式适用范围在盾构机头前后±2L距离处，对指导实际盾构施工具有重要意义。

Since installing the first TDL-10 in 1996, Western Cutterhead has installed three more Cincinnati Machine Arrow 750 machining centers, requiring Troyke TDL-10-2 tandem tilting rotary tables.

自从安装第一个10 TDL在1996，西Cutterhead安装更多的3 辛辛那提机器箭750 机器加工中心，要求Troyke TDL 10 2 串行倾斜旋转桌子。

It is shown that the friction force and bulkhead thrust are the main factors of shield thrust setting, while the friction between the cutterhead and soil is the main factors of cutterhead torque setting. Friction force between shield and soil would make front soil of shield upheave, and subsidence of surface soil is induced by ground loss when the friction force between the cutterhead and soil results in the surface settlement asymmetrical distribution.

通过计算发现，盾构施工中盾壳摩擦和正面推力是盾构推力设置的主要因素，而刀盘与土体摩擦是刀盘扭矩设置的主要因素，盾构前方土体隆起主要由盾壳摩擦引起，刀盘摩擦作用主要引起地表沉降的非对称分布，地表沉降主要由盾尾空隙产生。

I use an example quoted by Hu Jiaqi:"It is reported that America separates the DNA of a kind of virus by making use of genetic technology and combines it with another kind of DNA. Finally, they get a kind of virulent biological agent called a "pyrotoxin". Someone discloses in private that 20 grams of such a kind of biological agent could result in the global death of 6 billion people due to infection."

我在这里例举胡家奇所引用过的例子："据报道，美国利用转基因技术，将一种病毒的DNA分离出来，与另外一种DNA进行结合，拼结成一种剧毒的"热毒素"生物战剂，且私下有人透露，这种生物战剂只需20克，就可以导致全球60亿人全部感染死亡。"

Waiting, for the queers and the coons and the Reds and the Jews.
