在篦齿封严装置减振的开口阻尼环设计方法的基础上,对比研究了阻尼套筒的设计方法.采用动柔度法求解了安装有阻尼套筒的篦齿封严装置的动力响应.分析了阻尼套筒结构尺寸(厚度、接触面积)和安装过盈量等参数对篦齿封严装置动力响应的影响规律;在篦齿封严装置和阻尼套筒的组合结构中,存在最佳的阻尼套筒结构参数,此时阻尼套筒减振效果最佳;对组合结构不同的周波型振动,阻尼套筒的减振效果不同.
On the basis of the design method of the damping ring damping mechanism of the labyrinth sealing device, the design method of the damping sleeve is comparatively studied, and the dynamic response of the labyrinth sealing device with the damping sleeve is solved by the dynamic flexibility method. The influence of parameters such as the size of the damping sleeve (thickness, contact area) and the installation interference on the dynamic response of the labyrinth seal was analyzed. In the combined structure of the labyrinth seal and the damping sleeve, Of the damping sleeve structure parameters, then damping damping effect of the best damping; combination of different structure of the week-type vibration damping damping effect of different damping sleeve.
