摘要
为解决阀用位移传感器多目标多准则的电磁结构耦合优化设计问题,针对径向尺寸受到严格约束的长行程、高精度阀用位移传感器,运用MATLAB编写优化算法程序,得到以线性度和灵敏度为目标、以结构尺寸参数为约束条件的最优化参数匹配组。根据多目标优化结果,运用Maxwell电磁仿真软件对阀用LVDT进行等效建模,对优化模型和原始模型进行电磁场仿真分析,对比两者的输出特性。结果表明:优化模型的线性度为0.19%,灵敏度为23.12 mV/mm,较原始模型有较大的提高。该方法较完整地解决了LVDT结构优化设计,可为小型化阀用位移传感器的优化与设计提供参考。
In order to solve the problem of multi-objective multi-criteria electromagnetic structure coupling optimization design of valve displacement sensor,for the long stroke,high precision valve displacement sensor whose radial size is strictly constrained,the optimization algorithm program was written in MATLAB to get the optimal parameter matching group with linearity and sensitivity as the objectives and structural dimensions as the constraints.Based on the results of the multi-objective optimization,the equivalent modeling of the valve LVDT was carried out in the electromagnetic simulation software Maxwell,and the electromagnetic field simulation analysis was carried out on the optimized model and the original model to compare their output characteristics.The results show that for the optimized model,the linearity is 0.19%,and the sensitivity is 23.12 mV/mm.Compared with the original model,the optimized model has a great improvement.This method solves the optimization design of the LVDT structure in a more complete manner,and it can provide references for the optimization and design of the miniaturized valve displacement sensor.
