    摘要:

    目前運用較多的柔性運動副基本上只能產(chǎn)生微細變形,,適用于微動領(lǐng)域,缺少能產(chǎn)生宏觀尺度變形的柔性運動副。在彈性曲板變形理論的基礎(chǔ)上設(shè)計出一種新型柔性轉(zhuǎn)動副,,可以滿足宏觀尺寸下的變形要求,。通過理論分析建立其柔度矩陣,,分析其轉(zhuǎn)動剛度與轉(zhuǎn)動誤差,,利用Matlab進行了理論計算,,并進行了Ansys軟件仿真與實體模型試驗,。結(jié)果表明:理論計算與仿真的轉(zhuǎn)動剛度相對誤差為5.6%,轉(zhuǎn)動誤差相對誤差為3.4%,,通過試驗驗證了轉(zhuǎn)動剛度和轉(zhuǎn)動誤差相對角度變形的變化規(guī)律,,說明對該新型大變形柔性轉(zhuǎn)動副的柔度分析正確。

    Abstract:

    The disadvantage of current compliant pairs used in micro-displacement fields are that they produce micro-deformation rather than macro-scale deformation. In order to solve this problem, a new compliant revolute pair was proposed based on the theory of elastic deformation which can provide macro-scale deformation according to its own elastic deformation. The model of flexibility matrix was established, and rotation error was calculated with Matlab software and analyzed in Ansys. The results showed that the relative rotational stiffness error was 5.6% and relative rotation error was 3.4% according to the two methods. Finally, a test of the compliant revolute pair was carried out to justify the two above-mentioned results. It showed the flexibility analysis is reasonable.
