Because of swing of the radial labyrinth wreath with the shaft in main sintering fan, lead to the oil leakage problem of the bearing seat in LAIGANG sintering plant. 莱钢烧结厂烧结主抽风机原采用离心式迷宫密封,因离心密封环随轴向窜动引起轴承座漏油。
Conclusions: It appears that the most significant effect on contact stress of the radiocarpal joint occurs with a 4mm radial shortening ( RS) or more, and lead to significantly effect on wrist joint. 结论:桡骨远端骨折短缩4mm以上时,接触应力有显著变化,影响腕关节功能。
The stress and radial displacement will increase with the increment of half cone angle and lead. 正常工况下,螺旋输送器的最大应力强度和最大径向位移都随着半锥角和导程的增加而增大。
But in E grade of atmospheric condition, radial velocity of cloud cluster degenerated very slow and the vaporation of cloud cluster was not evident, which lead to LNG cloud cluster was with the heavy gas effect and was relatively difficult to enter into passive diffusion. E级大气条件下,径向速率衰减较慢,进入被动扩散的过程非常缓慢;LNG气化过程不明显,重气效应未完全消失,不利于LNG云团的稀释和冲淡。
According to the results, both the peak of circumferential stress and radial stress are all appeared in the corners area of the cavity die. Serious stress concentration and continuous cyclic high stress contribute to cracks initiation and growth and then lead to die failure. 从模拟结果来看,切向应力和径向应力峰值均出现在凹模内壁拐角处附近,应力集中较严重,容易导致模具的疲劳开裂。
If the target has a radial acceleration, conventional 2D-FFT based data processing method will lead to a Doppler Spread in Doppler domain. The high resolution of Doppler domain due to coherent integration no longer holds, which is very important in target detection of OTHR. 常规的二维FFT处理在处理机动目标时往往由于目标存在径向加速度而会在多普勒域造成多普勒扩展,从而无法应用相干积累带来的多普勒域的高分辨力完成对目标的检测。
Even a low radial velocity will lead to a severe distortion. 当目标有很小的径向速度分量时,也会造成成象严重失真。
For the effect of the grinding wheel feeding in hob radial direction, the regrinding error between the practical tooth edge and the theoretical tooth edge is formed, and the excessive regrinding error will lead to decrease the accuracy of gear. 受滚刀铲磨时砂轮径向进刀的影响,滚刀重磨后的刃形与理论设计刃形之间存在着重磨误差,过大的重磨误差将会导致滚切的齿轮精度不合要求。
But the method also has obvious disadvantages. The blade designed by the method is too twist. And the relative velocity grows too fast along the radial direction. For gas media, it will lead the Mach number to grow too fast. 但等环量流型也存在一些缺点,如叶片扭曲得很厉害,沿半径方向的相对速度变化较大,这对于气体介质来说,将导致马赫数较大。
At present, traditional processes of hob are radial relief grinding in general, when we adopt this process, it will cause tooth flanks distortion, reduce hob proper tooth profile, and be lead to hob accuracy lower, which restricts gear hobbing level further seriously. 目前滚刀一般采用径向铲磨方式进行精加工,由于径向铲磨会造成齿侧面畸变,减小齿形合格长度,导致滚刀精度寿命低,径向铲磨工艺严重制约着滚齿加工水平的进一步提高。
