摘　　要：为避免扭转振动可能造成的轴系疲劳损伤,设计了一款金属卷簧式减振螺旋盘,基于专业软件建立单元盘转子模型,对比卷簧式减振结构增加前后其静态和动态特性,验证卷簧结构的减振效果。结果表明:卷簧厚度的改变会呈现不同的减振效果,4 mm厚度卷簧结构的减振效果明显优于2.5 mm,且当卷簧结构固有频率与转子固有频率相近时,减振效果最为突出。Aiming at the fatigue damage of the shafting caused by torsional vibration, the coil spring type of metal vibration-damping spiral disk was designed.A unit disk rotor model was established based on software.By comparing the static and dynamic characteristics of the structures without and with vibration absorption, the effects of vibration reduction are verified.The results show that the change of the spiral disk thickness parameter will present different damping effects.The damping effect of 4 mm spiral disk is clearly better than 2.5 mm.And it is pointed out that when the natural frequencies of the vibration reduction spiral disk and the rotor are close, the vibration reduction effect is more prominent.
