摘要
微定位器是精密加工、纳米技术的重要组成部分,柔性机构则是微定位器的核心部件。本文利用有限元分析软件ANSYS对传统的基于柔性铰链的柔性机构和一种新的基于柔性悬臂梁的柔性机构进行了对比分析。分析结果表明,在相同的外形尺寸和作用力下,新柔性机构的输出位移增加了一倍,最大应力减少了23%。最后给出了一种新的基于柔性悬臂梁的柔性机构的设计方法,该方法可以减少设计参数并大大减少计算量。
Micropositioner is an important part of the precise manufacturing and nano technology, and the flexible mechanism is the essential component of the micropositioner. By using the finite element analysis software ANSYS, the analysis and contrast of the traditional flexible mechanism based on the flexible hinge and a new flexible mechanism based on the flexible cantilever beam are carried out. The results show that the output displacement of a new flexible mechanism is twice that of the traditional one at the same size and force, while the biggest stress decreases by 23 %. Finally a new flexible mechanism design method based on the flexible cantilever beam which can decrease the parameters and calculation is presented.
