This study is focused on the dynamic characteristics of a vertical turbo molecular pump rotor-bearing system. The research methods can be divided into two parts, which are numerical analysis and experimental measurements. In numerical analysis, we use the finite element analysis software ANSYS and DyRoBeS to construct a two-dimensional and three-dimensional model of the rotor-bearing system. In the analysis process, by constantly changing the pump system assembly methods we can correct and verify the rotor-bearing system finite element model under different boundary conditions. Next, we calculate the Campbell diagram to understand the dynamic characteristics of the rotor-bearing system, and to compare with the experimental results to verify the model. Finally, we found the relationship between the rotor critical speed and the bearing stiffness in order to provide the design of the molecular pump rotor and the bearing system. Experimental measurements were divided into two parts: static percussion tests and dynamic measurements. Static test can provide the natural frequencies of the rotor-bearing system. Waterfall diagram of the dynamic test can measure the pump system’s critical speed from zero speed up to the working speed crossing, and to insure that the pump working speed is far from the critical speed of 10% in the safe range. In summary, the results of the experimental measurements and numerical analysis can be the basis for the design of the turbo molecular vacuum pump rotor-bearing system analysis techniques in order to identify and prevent pump vibrations.

This paper presents the scaling laws that provide the geometry and dynamic similitude conditions between the damped rotor-shaft system and its scale model, so that the torsional vibration characteristics of the full-size rotor-shaft system can be predicted from those of its scale model. The last scaling laws are determined from the equations of motion of the full-size rotor-shaft system and its scale model. Then, the scaling factors, that establish the relationship between the last two systems, involved in the preceding scaling laws (i.e., explicit scaling factors) are determined according to the fundamental physical properties of each scalable parameter of the system, while those not involved in the scaling laws (i.e., the implicit scaling factors) are determined based on the theory of dimensional analysis. Both the free and forced torsional vibration characteristics of the full-size rotor-shaft system and those of its scale model are used to validate the presented scaling laws and scaling factors.

The object of this paper is to study how to predict the lateral vibration characteristics of the full-size rotor-bearing system by using the scale rotor-bearing model and the associated scaling laws, such that one may significantly reduce the time and money required by the experiments. To this end, the scaling laws for all the relevant parameters regarding the full-size rotor-bearing system and its scale model (such as, sizes of the constituent members, spring constants and damping coefficients of the supports, natural frequencies (of free vibration) and forced-vibration displacements, etc.) are derived first from the equations of motion of the last two systems. Next, the scaling factors for all relevant parameters of the above-mentioned two systems are determined with the theory of dimensional analysis. Now, based on all of the above-mentioned relevant parameters of the full-size rotor-bearing system, one may determine the corresponding parameters of the scale rotor-bearing model by using the associated scaling factors and predict the vibration characteristics of the full-size rotor-bearing system by using the corresponding ones of the scale rotor-bearing model. Finally, the influence of constituent-member sizes on the similarity of natural frequencies (of free vibrations) and the influence of spring constants, damping coefficients and external loads on the similarity of dynamic responses (of forced vibrations) are investigated. Because the literature concerning the use of scaling laws and scale rotor-bearing model for predicting free and forced vibration characteristics of full-size rotor-bearing system is rare, this paper provides a complete and systematic theory and technique in this aspect. Keywords: full-size rotor-bearing system, scale rotor-bearing model, scaling laws, scaling factors, lateral vibration characteristics

This thesis is concerned with the dynamic analysis of a geared rotor-bearing system. A finite element model of the geared rotor-bearing system is developed by taking account of the lateral-torsional coupling effect to obtain the natural frequencies, mode shapes, and the steady-state responses. From the response time histories, the FFT spectra can be obtained to investigate the effects of dynamic coupling terms under different grades of balance quality and spin speeds. In addition, the lateral response due to short circuit torque is examined to be substantial for the turbo-generator set. The nonlinear dynamic behavior of a geared system supported bysqueeze-film dampers is also investigated. The FFT spectra, Poincare maps and bifurcation maps are made to classify the responses whichinclude sub-harmonic, superharmonic, quasi- periodic, and chaotic responses. The hybrid technique of the Harmonic Balance Method and Time Collocation is employed to obtain the stability of the first variation equations with periodic coefficients, which is generatedby the perturbation technique.
