中文摘要: 针对空间载荷平台上的振动抑制需求,研制了一种新型模块化的液电混合作动器。首先, 提出了液压阻尼模块、音圈电机模块和测量模块串联的混合作动器的总体结构;其次,分析了液压阻尼模块在细长孔中的阻尼变化影响因素及其力变换关系;再次,以出力密度为优化目标,采用电磁有限元分析软件进行了优化仿真分析,优化了音圈电机模块的结构参数;最后,进行了出力和出力平稳性测试。结果表明,该作动器能够在作动器全行程内实现平稳的力输出,出力密度达到3.87×10^-4 N/mm^3。
Abstract:To meet the requirements of the space load platform’s vibration depression, a novel modularized active-passive hybrid actuator is developed. First, a general structure with a passive hydraulic damping module, a voice coil motor module and a displacement measurement module in serial is proposed. Second, the influence of damping hole structure parameters on the damping coefficients and force transform of the damping module are analyzed. Then, the simulation is carried out using finite element analysis software to optimize the voice motor’s structure parameters for enlarging the output force density and force stability. Finally, the output force is tested to verify the effectiveness of the design. The experimental results indicate that the actuator can achieve smooth force output throughout its full stroke, with an output density of 3.87×10^-4 N/mm^3.
