查询词典 tool bogie

The truck cast steel three big piece type bogie is easy to maintain. But since the grate weight under spring and the large operation strength during running, it is difficult for the bogie to keep the positive position. The critical speed of the snaking motion is low, which is inapplicable for high speed running. The other type of truck bogie is H type integrative truss. Its structure is complicate relatively, which is not easy to manufacture and maintain. But it can keep the positive position of the bogie preferably. And because it is adopted the structure of axle box one series elastic suspend, the weight under spring reduces. Which achieve the effective control to wheel sets and improve the running quality of the bogie distinctly.

货车铸钢三大件式转向架便于制造维修，但因其簧下质量大，在运行中轮轨作用力大，转向架难以保持正位，蛇行运动临界速度低，不适用于高速运行；货车转向架的另一种形式是"H"型构架一体式，结构较为复杂，不便于制造和检修，但它能够较好地保持转向架的正位，而且由于采用了轴箱一系弹性悬挂结构，降低了簧下质量，实现了对轮对的有效控制，明显地改善了转向架的运行品质。

At this point, you can select the move tool, place a check mark in the tool options in the "" automatically select the layer, so that in addition to the slice tool, the path component selection tool, the pen tool and start tool, the other tools in the Toolbox to the currently selected, press and hold the CTRL key, the current tool will temporarily become mobile tool, click on any of the objects on the canvas, Photoshop will automatically go to the layer so that you can perform an operation.

这时，你可以先选择移动工具，在工具选项中勾选"自动选择图层"，这样，除了切片工具、路径组件选择工具、钢笔工具和抓手工具外，工具箱中的其它工具为当前所选时，按住Ctrl键的同时，当前工具都会暂时变成移动工具，点击画布上的任意对象，Photoshop都会自动转到其所在图层，这样就可以进行操作了。

The effect of the tool composition on the friction and wear behavior was investigated,and the morphologies of the rake face and rear face of the tool cutting the steel in air and nitrogen were observed on a scanning electron microscope. It was found that the Al_2O_3/TiB_2 tool was dominated by adhesive and abrasive wear in low speed dry cutting; while in high speed dry cutting,the tool was characterized by oxidation wear. An oxide layer of TiO_2 was formed by way of the oxidation of the reinforcing agent TiB_2 at a very much high cutting temperature, which contributed to greatly reducing the friction coefficient and increasing the antiwear life of the tool.Such a friction-reducing and antiwear behavior of the oxide layer was enhanced with increasing content of TiB_2 in the tool composite. However,the tool showed a relatively poorer wear resistance in N_2 than in air, because N_2 acted to retard the oxidation of the TiB_2 and the formation of the oxide layer on the tool rake face.

结果表明：低速干切削时，Al2O3/TiB2陶瓷刀具的磨损机制主要表现为粘着磨损和磨料磨损；而在高速干切削时，刀具的磨损机制主要表现为氧化磨损，刀具表面经由氧化反应生成具有润滑作用的反应膜而起到固体润滑作用，从而使刀具的耐磨性能提高，随着TiB2含量和切削速度的增加，反应膜的减摩抗磨作用增强；而在切削区通入氮气时，由于刀具表面氧化膜形成受阻，刀具的抗磨能力有所降低。
