针对电磁阀传统设计方法中，产品设计周期长、试制实验费用高等问题，本文采用有限元方法在产品设计初期对电磁阀的性能进行预测。首先，运用Ansoft Maxwell软件分别建立了电磁阀的三维与二维有限元模型，进行了磁场分析与电磁力计算，通过比较发现三维模型与二维模型计算结果与测试结果均吻合较好。最后，在二维模型的基础上，运用Maxwell软件的参数化设计功能进一步分析了不同初始间隙、不同驱动电压对电磁力的影响。结果表明，基于Maxwell的电磁阀有限元仿真能够在产品的设计初期快速地预测电磁阀的性能，为电磁阀的设计与优化提供理论指导。

Problems exist in traditional design method of a solenoid valve, such as long design period of product and high cost of trial-manufacture experiments. Finite element method is adopted to forecast the performance of the solenoid valve at the beginning of the product design in this paper. Firstly, three-dimensional and two-dimensional finite ele-ment models of the solenoid valve are established respectively by Ansoft Maxwell software. Magnetic field analysis and electromagnetic force computation are finished. By comparison, the calculated results of three-dimensional and two-di-mensional finite element models are consistent with the test results. Finally, based on the two-dimensional model, the impact of different initial gaps and drive voltages on the electromagnetic force are further analyzed. The results show that the finite element simulation of solenoid valve based on Maxwell can help to forecast the performance of the sole-noid valve quickly at the beginning of the product design,which provides a theoretical basis for the design and optimi-zation of the solenoid valve.
