On the Transient Response of a Spinning Disk Under a Space-Fixed Load

Abstract

The titled problem is studied analytically by an eigenfunction expansion method. In the early stage following the excitation, symmetric deformation is observed when the rotation speed is around the first critical speed. At a rotation speed ten times higher than the first critical speed, at which the convective velocity of the media is comparable to the wave propagation speed, asymmetric deformation becomes apparent.
