Abstract :
A simplified dynamic model of a multiple disk and spindle assembly is discussed in this paper. The model is particularly focused at describing the coupling between spindle and disk motion, therefore it is suitable for the design of a spindle motion control aimed at minimising the vibrations of the disks. The model has been validated by comparison of the resonance frequencies obtained by simulation with experimental results, available in the literature
