Analytical Algorithm and Structural Optimization of Transmission Characteristics of Cylindrical Permanent Magnet Couplings
摘要
Abstract
The permanent magnet couplings had problems of complex structure,difficult assem-bly and poor resistance to eccentric load.In terms of transmission performance evaluation,the finite element simulation calculation took a long time and the analytical calculation accuracy was low.There-fore,a new type of cylindrical permanent magnet coupling configuration was designed.The trapezoidal magnet and the wedge slot may realize the self-priming assembly of permanent magnets.Aiming at this configuration,an equivalent magnetic charge-magnetic circuit analytical calculation method was proposed to calculate the transfer torque and an absorption-repulsion composite permanent magnet coupling configuration was designed.The transfer torques where the relative deflection of inner and outer rotors as 0°～45° and the foces responde to radial relative offset-3.8～3.8 mm of two perma-nent magnet couplings were simulated and verified by experiments.The results show that the errors of the proposed analytical algorithm decreases 50％than that of the simulation results,and the analytical calculation time is shortened from 2 h to 2 min.Compared with cylindrical configuration,the maxi-mum radial eccentric load of the suction-repulsion composite configuration is as 48.59％.Reasonable suggestions are put forward for design optimization of permanent magnet couplings.关键词
