本文针对电磁直线式主动悬架作动器电磁波动力大、有效输出力低的问题，设计了一种多目标粒子群参数优化算法。建立了作动器有限元模型，通过径向磁通密度的理论计算和有限元仿真值作对比，验证了有限元模型的正确性。对作动器的槽口宽度、初级边端长度和极距长度进行参数敏感度分析和多目标粒子群优化，并对比分析了优化前后作动器的输出力、反电动势和波动力。最后试制了物理样机并开展了阻尼力特性试验和电磁力特性试验。仿真结果表明：当电磁作动器的结构参数通过优化后，有效电磁力、总谐波畸变量和电磁波动力均得到了改善。试验结果表明：阻尼力波动试验值与仿真值基本一致，平均电磁力试验值和仿真值随电压变化呈线性分布且误差较小。
Abstract
In this paper, a multi-objective particle swarm optimization algorithm is designed to solve the problem of large electromagnetic wave force and low effective output force of linear active suspension actuator. The finite element model of the actuator is established, and the correctness of the finite element model is verified by comparing the theoretical calculation of the radial magnetic flux density with the simulation results. The notch width, the edge length and the pole distance of the actuator are Sensitivity analysis and multi-objective Particle swarm optimization, and the output force, back electromotive force and wave force of the actuator before and after optimization are compared. At last, the physical prototype is manufactured and the damping force and electromagnetic force characteristics are tested. The simulation results show that when the structure parameters of the electromagnetic actuator are optimized, the effective electromagnetic force, total harmonic distortion and electromagnetic wave force are improved. The test results show that the test value of damping force fluctuation is basically consistent with the simulation value, and the average electromagnetic force test value and the simulation value vary linearly with the voltage and the error is small.
