Research For Superconducting Gyroscope Rotor's Rotational System

The superconducting gyroscope is one kind of high accuracy magnetism floated-type gyroscope.It works using some characteristics of superconductor under low temperature . The superconducting gyroscope has the very high precision (2-3 magnitude higher than conventional gyroscope) and the stability. It is the important strategic sense to national defense enterprise of our country to research on superconducting gyroscope .The research in the dissertation mainly focus on the rotational system of the superconducting gyroscope rotor .It is a part of the research about high accuracy superconducting magnetism floated-type gyroscope ,that is an advanced research project of national defense in the Tenth Five-Year Program.This dissertation has elaborated the Meissner effect of the superconductor in the superconducting condition, and has explained the superconductor's Meissner effect with the London theory. Then ,it has explained that the metal niobium is used as the superconducting gyroscope rotor's material. It has analyzed several kind of plans about the starting rotation of the superconducting gyroscope rotor - exchanging rotary magnetic fields, a helium air current, the superconducting electromotor . The plan about the superconducting electromotor, has contained two kinds of plans. This dissertation has analyzed them. Finally ,it has chosen the appropriate plan in this project, namely the improved plan of the second kind of plan about the superconducting electromotor, to the starting rotation of the superconducting gyroscope rotor.Then, it has designed the structure of the superconducting gyroscope rotor basing on this plan.In the structural design of the superconducting gyroscope rotor,it has selected the plan that stator coil have three pairs and the rotor have four slots. It has analyzed the stress and the energy conversion of the starting rotation of the superconductivity gyroscope rotor. Basing on the structure of the superconducting gyroscope rotor, it gains the formula between the phase's changing frequency of the stator coil and the rotational speed of the superconducting gyroscope rotor.Then,it has analyzed the...
