模块化液电混合作动器的出力密度优化
Output Force Density Optimization of Modular Hybrid Actuator
摘要
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 co-efficients 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 3.87×10-4N/mm3.关键词
