| Abstract: | Based on the theory of magnetic field, the method of calculating magnetic gap and its work principle on permanent magnetic vibration generators were introduced. Example for series AS-VA0.6, magnetic gap flux density was checked out, and simulation of the finite element of static magnetic field was derived to solve, according to the results of calculation, simulation and measure on magnetic flux density, its were consistent with the known facts. Finally, discussion to optimize and analyze simply on magnetic field by method of the finite element to guide the design of vibrator. |
