The magnetic circuit calculation of an electric vibration table is an important part of the design phase,and the air gap magnetic induction intensity and table magnetic flux leakage are two important performance indicators.In the design stage,it is of great significance to accurately calculate the air gap magnetic flux density distribution and table magnetic flux leakage of the electric vibration table,which is conducive to shortening the research and development cycle and reducing research and development costs.In this paper,a 10kN thrust electric vibration table is taken as an example,and the finite element method is used to calculate the air gap magnetic flux density distribution and table magnetic flux leakage.Compared with the measured data,the final results show that the simulation results of the average air gap magnetic flux density are close to the measured results,with an error of only 1.3%,and the error between the simulation results of table magnetic flux leakage and the measured results is 29.3%.
