rotation vibration meaning in Chinese

旋转振动

Rotation vibration energy
转动振动能量
Rotation vibration spectrum
转动振动谱
The results of calculation and measures show that the low frequency of steam pipelines vibration fastens on 4 . 3 to 4 . 5 hz and 9 . 5hz , the low modes fastens on one - steps curl in vertical plane and its plane of each steam pipeline and one - rotation along with the line connecting the port circling main steam gate and the horizontal port of unit . the modes of # 3 and # 4 main steam conduits occupy the majority of low steps modes ( the five of the first eight phases ) , except for the first phase rotation vibration , the maximal distortion of other low steps vibration modes are all caused by the vibration of erect pipelines of cylinder
计算和实际测量结果表明：导汽管低频振动以4 . 3 - 4 . 5hz 、 9 . 5hz频率为主，管系的低阶模态以各导汽管在垂直导管平面和平面内的一阶弯曲、以及绕主汽门处端点与水平段汽机端连线的一阶扭转为主， # 3 、 # 4导汽管的振动模态占低阶模态的多数(前八阶模态中的五阶) ，除一阶扭转振型，导汽管的其它低阶振动模态中都是进汽缸立管的下端振动变形最大。
