Electromagnetic Simulation and Optimization of High-speed Pneumatic Solenoid Valve

传统的电磁阀设计主要依靠参数化模型来计算分析,参数化模型的精度并不是很高,对于产品的设计偏差较大,产品设计周期长、实验费用高。该文采用有限元数值仿真的方法对产品性能进行预测。首先运用Maxwell软件建立了电磁阀的三维静态模型,进行磁场的分析与电磁吸力的计算,然后通过仿真结果跟实验结果的对比验证了仿真模型的正确性,在此基础上对不同的结构参数和电气参数进行分析优化。结果表明基于Maxwell的有限元电磁仿真模型能够快速预测产品的性能,为产品的开发设计优化提供了很好的支持。

The traditional design method of the solenoid valve is often based on parametric analysis model. Precision of parametric model is not very high and the products based on it is not very ideal. What＇smore,the traditional design method dues to long product design cycle and high cost of experimentation. In this paper,finite element method is adopted to forecast product performance. Firstly,three-dimensional static model of the solenoid valve is built up by Maxwell to analysis magnetic field and calculate the electromagnetic force. Then verify the correctness of the simulation model by comparing simulation results with experimental results. On these bases,analysis and optimization were done for different structural parameters and electrical parameters. The results show that the finite element electromagnetic simulation model based on Maxwell can quickly forecast the performance of the product,in order to provide good support for design and optimization of product.
