New Rotor Micro-Gyro Ball Disc Rotor Structure Design

Micro gyroscope has an important role in today’s society more and moreimportant, its development by leaps and bounds, but there are some problems.Among them, due to the use of magnetic suspension rotor micro gyroscope eddycurrent effect, the heat will be low lateral stiffness of the rotor also limits it s speedincrease; And electrostatic suspended gyro although accuracy is very high, butprocessing cost is high, the high electrostatic voltage required support shortcomings.Aiming at the shortcomings and disadvantages, this article mainly from thebreakthrough on the rotor structure, so as to realize relatively simple structure, lowcost, high speed, high precision of the new type of gyroscope.Based on the related basic principle of liquid floated gyro proposed new balldisc rotor, using SolidWorks, such as Ansys, Workbench, Fluent software based onrotor model, finite element analysis and the friction between the rotor and stator,size optimization.First of all, use SolidWorks for system modeling, the preliminary design size,examining interference and other issues.Second, using Ansys finite element analysis was carried out on the rotor itself,applying the boundary conditions, respectively to the rotor by stress, producingstrain, and its modal analysis. Investigation into the feasibility of this struct ure,prove its advantages.Then, use the Workbench and Fluent respectively to examine the rollingfriction between the stator and rotor viscous force produced by liquid flow, will be acombination of analysis, it is concluded that the rotor stator gap and the status of thefloating liquid on the rotor high-speed rotation of the influence of friction resistance.Finally combining the result optimization design of the rotor size. Make asimple structure, simplify the control circuit, convenient processing, low cost highprecision gyroscope.
