Magnetic Circuit Simulation of 10kN Thrust Electric Vibration Table

电动振动台磁路计算是电动振动台设计阶段的重要一环,气隙磁感应强度和台面漏磁是其两个重要性能指标。在设计阶段准确计算出电动振动台气隙磁通密度分布和台面漏磁具有重要意义,有利于缩短研发周期和减少研发成本。本文以10kN推力电动振动台为例,采用有限元法计算其气隙磁通密度分布和台面漏磁,并以实测数据进行对比,结果表明:气隙平均磁通密度仿真结果与实测结果接近,误差仅为1.3%;台面漏磁仿真结果与实测结果误差为29.3%。

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%.
