摘要
分析了二维微动平台由于机构原因产生的两向间位移耦合现象,提出了一种采用线切割方式加工、具有对称式复合柔性四杆机构的微动平台结构形式,并使Y向平台完全镶嵌在X向平台内。通过理论分析和实验测试,其结果理想,为较好地解决二维微动平台两向间位移耦合问题提供了有效方法。
The coupling phenomena of displacement generated between twain directions of 2D jogging platform due to the reason of mechanism was analyzed, a kind of jogging platform structural form that possessing the symmetrical typed complex flexible four-bar linkage to be machined by adopting the manner of electron discharge machining was put forward, and letting the Y directional platform be totally embedded inside the X directional platform. By means of theoretical analysis and experimental test, the result was to be ideal, thus an effective method was provided for better solution on the displacement coupling problems between twain directions of 2D jogging platform.
