M.Ing. (Mechanical Engineering) / This thesis is about the design of a suitable suspension system for a high-speed machine. Experimental parametric analyses of some aspects of the design are presented. Some rotordynamic aspects which are addressed include the following: Undamped lateral critical speed analysis in order to determine the stiffness requirements for the suspension system of the machine. Calculation of optimum damping for the rotating system and an experimental evaluation of the amount of damping on the dynamic behaviour of the machine. Design of the suspension system from a dynamics point of view. Design of a test rig to evaluate the performance of the squeeze-film damper. Experimental parametric evaluation of a squeeze-film damper without seals or oil supply groove.
