In our previous research, four non-uniform contact types and SMEs were studied firstly to simulate the possible non-uniform contact statuses induced by the real machined motor rotor. By inspecting the results of the non-uniform contact analyses, different incomplete contact type rotors with different contact rates will be designed accordingly in this paper. The designed method is to make gap slots...
This paper employs a hybrid numerical method combining the differential transformation method (DTM) and the finite difference method (FDM) to analyze the nonlinear dynamic behavior of a rigid rotor supported by an elliptic gas bearing system (EGBS). The results obtained for the orbits of the rotor center are in good agreement with those obtained using the traditional FDM approach. Moreover, the results...
A polarimeter based on Stokes-Mueller formalism and rotating-wave-plate Stokes polarimeter is successfully developed to measure the optical rotation angle in a chiral medium. The average relative error in the measured rotation angles of glucose solutions with concentrations ranging from 0 to 1.2 g/dl is determined to be 3.78%. The correlation coefficient between the measured rotation angle and the...
This paper employs differential transformation method (DTM) to study the dynamic behavior of a gyroscope control system. The analytical results reveal a complex dynamic behavior comprising periodic, sub-harmonic, quasi-periodic, and chaotic responses of the center of gravity. Furthermore, the results reveal the changes which take place in the dynamic behavior of the gyroscope control system as the...
