11. Summary and Conclusions

This book is devoted to the study of dynamic properties of rotating machinery by means of numerical and experimental calculation methods. Dynamic properties of rotating machinery are understood to be the stiffness, damping and mass coefficients of the rotor–bearing system. The main aim of the work was to develop an experimental method of determining the dynamic coefficients of radial hydrodynamic bearings and to calculate the values of dynamic coefficients of bearings on the basis of experimental tests as well as linear and non-linear numerical methods. Experimental tests were carried out on a laboratory test rig with a rotor supported on two hydrodynamic radial bearings.
