torsional oscillation

基本解釋

"The torsional oscillation ... pattern for SolarCycle 24 first appeared in 1997, " Hill said today during the pressbriefing.
“第24太陽活動周期的…扭曲振蕩模式首次于1997年出現，”希爾在簡報會上說道。
The causes and essence of the torsional oscillation of large turbogenerator which consider as a kind of complex open system was investigated by using nonlinear science theory.
將大型汽輪發(fā)電機系統作為一類復雜開放系統，基于非線性科學分析了該系統的動力學特性，論述了該系統軸系扭振的原因及其本質。
A mechanic system of torsional oscillation consists of helicopter' s engine , drive systenu rotor and tail rotor. This torsion-al system is also coupled with the fuel control of turbine engine.
直升機的發(fā)動機通過傳動系統驅動旋翼及尾漿，形成了一個機械扭振系統，這個系統又與發(fā)動機控制系統相互耦合構成一個閉環(huán)的動力學系統。

扭振
The torsional oscillation problem will make the shaft endure big torque time and again, which produces the fatigue life loss and even makes the shaft broken.
機網扭振相互作用會使機組軸系反復承受較大的扭矩,從而造成疲勞壽命損耗、甚至直接損壞。
