| 摘 要： | 为解决某超高速转子系统的失稳碰摩问题,以干摩擦阻尼耗散转子涡动能量理论为依据,采用一种自由安装式干摩擦片减振结构(干摩擦阻尼器).该结构在转轴上安装波形弹性垫片及干摩擦片,通过螺母预紧力矩向波形弹性垫片及各干摩擦片提供轴向正压力.干摩擦片随转子振动并产生相对运动,从而耗散转子涡动能量,达到减振、增强转子稳定性的目的.通...

| Abstract: | A kind of freely assembled dry friction vibration absorber was presented to solve the problems of instability and rubbing faults for a super-high speed rotor system based on theory of dry friction dissipating energy from rotor vibration.In this structure,a wave-shaped elastic pad and some dry friction pads were freely assembled on shaft,and axial normal force was provided for elastic pad and dry friction pads by pre-loaded moment for nut.When friction pads moved with shaft,the relative movements between the... |
