The objective of the analysis which follows is the deriva tion of simulation models for flexible spinning bodies. The analysis employed is based on relatively simple con cepts of vector mechanics and results in a lumped-param eter simulation model. The simulation models which are first derived are subsequently simplified by invoking the small deflection assumptions of the theory of elasticity. A final section deals with some analysis steps used in adapting the basic simulation model for the description of turbine rotors.
