低損耗磁懸浮電主軸的動態(tài)性能研究
[Abstract]:Magnetic levitation motor spindle has the advantages of high limit speed, no contact wear and no lubrication. It is suitable for ultra-high speed machining. However, due to copper and iron loss, the heating problem of magnetic levitation spindle is serious. In order to simplify the cooling of the system, the same pole radial magnetic bearing and axial permanent magnetic bearing are introduced into the magnetic suspension motor spindle in order to reduce the power consumption and heat generation. In this paper, a test device for low loss magnetic levitation motorized spindle is designed and manufactured, including electrical control system and mechanical parts. The main design parameters of each link of the system are given. The calculation model of axial permanent magnetic force of permanent magnetic bearing is established by using the method of equivalent magnetic charge. The variation of axial permanent magnetic force with air gap is analyzed by numerical calculation. The magnetic field distribution and power loss in the same pole radial maglev bearing and rotor are calculated by finite element analysis software ANSYS10.0. The dynamic performance of the low loss magnetic levitation motorized spindle system is simulated by the dynamic analysis software ADAMS and the scientific and engineering calculation software MATLAB. On the basis of theoretical calculation and simulation analysis, the dynamic performance of maglev motorized spindle is studied by hammering excitation and high speed rotation of the system. The results show that the magnetic levitation motor spindle designed in this paper can smoothly cross the first two critical speeds of the system and operate stably in 40000r/min with a maximum amplitude of 7 渭 m. The same pole radial magnetic bearing and axial permanent magnetic bearing can guarantee the good dynamic performance of the magnetic suspension motor spindle, and the system structure is simple, and the power consumption and heat generation are relatively small.
