1·Addition of chamfering shape on seating surface of joint bolt at atf cooler pipe area.

棱 增加物的塑造在自动制冷管的范围内、接头螺栓的座套表面。

2·Under certain pre - tension from flange joint bolt, leakage of flange sealing had an obvious decrease, thus resolving sealing failure in cover flange of heat exchange.

在一定法兰连接螺栓预紧力作用下，法兰密封泄漏明显减少，从而解决了热交换器封头法兰密封失效的问题。

3·As the bolt tension increase, the tension of rail web, stress of joint bar and stress of joint bolt would increase accordingly, but the displacement of rail would become smaller.

螺栓扭矩增大，接头区钢轨轨腰拉力、夹板应力、螺杆内应力都会增大，而钢轨位移会随着螺栓扭矩的增大而减小。

4·Based on the 3D analysis result, shear models of ring joint bolt is built and shear parameters between rings needed in 2D analysis with beam-spring model can be obtained by this shear model.

然后，在对三维有限元分析结果研究的基础上，建立了环缝处的纵向螺栓剪切模型，利用该模型可以计算得到错缝拼装衬砌二维梁-弹簧模型中环间剪切弹簧的刚度；

5·To guarantee the reliability and security of the steel construction, the clamp load of the joint bolt should be under strict control, sometimes even the tension of the bolt should be measured on-line.

为确保钢结构工程的可靠性和安全性，必须严格控制连接螺栓的预紧力，必要时还要在线监测螺栓工作应力。

6·Undo hexagon-head bolt on universal joint.

旋开万向节上的六角头螺栓。

7·Between the motherboard of engine room and upper tower, each section of tower, tower is connected with conduction joint except for its own bolt union.

机舱底板与上段塔架之间、塔架各段之间、塔架除本身螺栓连接之外还增加了导体连接。

8·In the connection design of steel structure, the shear plate with high-strength bolt connection is extensively used at the flexible joint where the beam is connected to the weak axis of the column.

钢结构节点设计中，梁与柱弱轴方向的柔性连接常采用剪力板高强螺栓连接，螺栓群所承受的荷载有竖向力和偏心力矩。

9·As the main conjunctive mode of the steel structure, high-strengthened hexangular bolt joint auxiliary has got widely used in production.

高强度大六角螺栓连接副作为钢结构的主要连接方式，在生产中得到了广泛的应用。

10·Its flange USES the bolt joint.

其法兰处采用螺栓联接。
