摘要
电磁作动器作为振动主动控制的核心部件,设计一款基于Halbach磁极阵列的新型安培力式电磁作动器,具有高力密度和低输出力波动率的特点。分析电磁作动器的多物理场耦合关系,建立电磁场-能耗场耦合优化模型,其中能耗场采用神经网络代理模型建模方法以提升计算效率;采用非支配排序遗传算法Ⅱ开展多目标优化设计,结合熵权逼近理想解排序法获取最佳设计参数组合。试制电磁作动器样机并开展试验分析,结果表明:电磁作动器在30.0~250.0 Hz频段内,电磁力常数可达20 N/A,非线性度小于10%;在250.0 Hz峰值正弦激励电流8 A时电磁作动器能耗为105.20 W,具有力衰减率低,线性度良好和低功耗的优势。
As the core component of active vibration control,a novel Ampere force electromagnetic actuator based on the Halbach magnetic pole array was designed,featuring high force density and low output force fluctuation rate.The multi-physical field coupling relationship of the electromagnetic actuator was analyzed,and a coupled model of the electromagnetic field and energy consumption field was established.In this model,the energy consumption field was modeled by the neural network surrogate model method to enhance the computational efficiency.The non-dominated sorting genetic algorithmⅡoptimization algorithm was employed to conduct multi-objective optimization design,and the improved entropy weight decision-making theory was combined to obtain the optimal combination of design parameters.A prototype of the electromagnetic actuator was fabricated and experimental analysis was carried out.The results show that in the 30.0-250.0 Hz frequency band,the force constant of the actuator can reach 20 N/A,and the nonlinearity is less than 10%.When the peak current is 8 A at 250.0 Hz,the energy consumption of the actuator is 105.20 W,presenting the advantages of low force attenuation rate,good linearity,and low power consumption.
