讨论了一种由两个对抗磁体共用一个永磁体磁芯组成的电磁软执行器的优化设计问题。首先，计算磁场和施加力的螺线管与永磁柱塞作为该电磁致动器的主要组成部分。讨论了在功率消耗有界的情况下，考虑线圈的长度、内径、平均直径、匝数和封装密度等几何参数对线圈的优化设计。致动器的大小对合力的影响，并讨论了缩放的限制。然后，由于致动器的组件的软性质，横截面的影响，即横向变形的致动器上的磁场在截面中心的调查以及。由于横向载荷的作用，致动器可能会发生变形，特别是当致动器由柔性材料制成时。(C)2018 Elsevier B.V.版权所有。
This paper discusses design optimization of an electromagnetic soft actuator composed of two antagonistic solenoids that share a permanent magnet core. First, calculation of the magnetic field and applied force of a solenoid with a permanent magnet plunger is presented as the principal component of this electromagnetic actuator. Design optimization of the coil is discussed considering the geometrical parameters of the coil, including its length, inner and average diameters, number of turns and packing density while the power consumption is bounded. The impact of the actuator size on the resultant force is presented and scaling limitations are discussed. Then, due to the soft nature of the actuator's component, the impact of the cross-section, i.e. lateral deformation of the actuator on the magnetic field at the center of section is investigated as well. The deformation might happen to the actuator due to the load in the transverse direction, especially when the actuator is made of flexible materials. (C) 2018 Elsevier B.V. All rights reserved.
