torsional oscillation

基本解释

"The torsional oscillation ... pattern for SolarCycle 24 first appeared in 1997, " Hill said today during the pressbriefing.
“第24太阳活动周期的…扭曲振荡模式首次于1997年出现，”希尔在简报会上说道。
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.
将大型汽轮发电机系统作为一类复杂开放系统，基于非线性科学分析了该系统的动力学特性，论述了该系统轴系扭振的原因及其本质。
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.
直升机的发动机通过传动系统驱动旋翼及尾浆，形成了一个机械扭振系统，这个系统又与发动机控制系统相互耦合构成一个闭环的动力学系统。

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.
机网扭振相互作用会使机组轴系反复承受较大的扭矩,从而造成疲劳寿命损耗、甚至直接损坏。
