| 摘 要： | 分析了弹支笼条局部断裂后对转子的影响;实验研究了弹支笼条没有裂纹、有裂纹时,升、降速等情况下转子的振动特性,包括有、无主动弹支干摩擦阻尼器控制等.实验发现,主动弹支干摩擦阻尼器能减小由于弹支发生局部断裂而增加的振动;选择P控制方案,主动式弹支干摩擦阻尼器能够在转子弹支局部断裂后,实现应急停机,起到保护转子系统的作用.

| Abstract: | The dynamic behavior of rotor systems with a cracked elastic support was analyzed.Experimental investigations of rotor vibration characteristics,in particular,caused by a crack in elastic supports by using the control of an active elastic support/dry friction damper,was carried out,It is proven that the damper is effective to reduce rotor vibration caused by cracked elastic supports.Experimental results show that the damper with the P control method,can be achieved with the emergency shutdown,and plays a ke... |
