摘要
以直流螺线管电磁阀为研究对象,利用电磁有限元软件Ansoft Maxwell对某种直动型电磁阀进行二维建模,并得出磁感应强度、磁力线分布图及静磁场下的吸力特性曲线。用正交设计法通过Ansoft Maxwell软件进行各指标的吸力计算,对得出吸力仿真计算值进行可靠性评估和因素分析;通过试验测试得到电磁阀吸力数据,对得出的吸力实测值也进行可靠性评估;后续对电磁阀吸力仿真计算值的可靠性评估和吸力实测值的可靠性评估进行了对比和分析。结果表明,通过改进仿真方法及缩小仿真计算时各因素取值范围,吸力仿真计算结果能真实地反映吸力可靠性。
A direct current solenoid valve was studied in this paper. Adopting finite element analysis software ＂Ansoft Maxwell＂ to build the 2D models of the solenoid valve, the magnetic induction intensity, mangnetic lines and suction curves under static magnet field were gained. The electromagnet suctions of all targets were calculated by orthogonal design method, using Ansoft Maxwell software; and then the reliability evaluation and factor analysis were applied on the simulation results. Also, the reliability evaluation was applied on the electromagnet suction data which were gained by testing. Finally, the simulation results and test data of electromagnet suction were compared and analyzed. The results proved that, after improving the simulation methods and narrowing down the range of each factor, the simulation results can authentically reflect the suction reliability.
