In order to study the coupling effect of bearing vibration on oil whirl. the motion mechanism of bearing vibration is analyzed. and the dynamic equation representing the effect of bearing vibration on oil whirl is established. It is pointed out that bearing vibration will change the boundary conditions of lubricating oil film and hence disturb the lubricating flow field. https://parisnaturalfoodes.shop/product-category/bladder-one-for-women/
