摘要/Abstract

摘要： 随着我国航天制造领域智能化要求的不断提升,利用工业机器人实现大部件的柔顺辅助装配对实现航天器的智能制造具有重要意义。然而在进行大部件的高精度装配时,机器人易受限于本体性能而难以弥补物理上的机械设计误差。据此,基于磁流变弹性体(Magnetorheological Elastomer,MRE)设计了一种可变刚度的被动柔顺装置置于机器人末端,并对其进行了仿真及实验测试,结果表明,升高通入电流可提高装置刚度,且装置在1 A电流差下的位移差约为20 %,适配柔顺辅助装配的不同过程。

Abstract: With the improvement of intelligent requirements in aerospace manufacturing field,using industrial robots to achieve flexible auxiliary assembly of large components is of great significance for realizing intelligent manufacturing of aerospace vehicles. However,limited by robots' own performance,it is difficult to compensate for physically mechanical coordination during the high-precision assembly of large components. Therefore,a passive compliant device with variable stiffness based on magnetorheological elastomers was designed at the end of the robot,after conducting simulation and experimental test,the results show that increasing the input current may enhance the stiffness of the device,and the displacement difference of the device under 1 A current difference is roughly 20 %,which can adapted to different processes of the flexible auxiliary assembly.

Key words: Magnetorheological Elastomers (MRE), passive compliant device, variable stiffness, flexible auxiliary assembly of large components
