【摘要】：柔性机构在精密加工领域的应用需求在逐渐增长,由简单形状的柔性铰链实现精确的微位移,但是目前柔性机构的精准控制尚未得到很好的解决。为此,提出一种基于有限元分析方法的标志区域建模方法,通过标志区域的划分及辨识来建立柔性机构模型,并通过仿真分析与有限元模型进行对比,接着提出了一种柔性机构模型降阶方法,最后通过应用柔性机构实例来说明了文中所用方法的有效性。
[Abstract]:The application demand of flexible mechanism in the field of precision machining is increasing gradually, and the precision control of flexible mechanism is not well solved by using simple flexure hinge to realize precise displacement. For this reason, this paper presents a modeling method of marking region based on finite element analysis method. The model of flexible mechanism is established by the division and identification of mark area, and the simulation analysis is compared with the finite element model. Then a model reduction method of flexible mechanism is proposed. Finally, the effectiveness of the proposed method is illustrated by an example of flexible mechanism.
