摘要
针对叠层压电陶瓷输出位移小,不能满足微驱动领域行程要求的问题,提出了一种采用三角形原理的放大机构。并对设计的三角形原理放大机构进行了理论放大倍数的计算,利用有限元分析法对放大机构进行了静力学和动力学分析,得到了三角形原理放大机构的应力分析云图和模态分析云图,验证了设计的合理性。
In view of the problem that the displacement of the laminated piezoelectric ceramics is small and cannot meet the requirements of the micro-drive field, the amplification mechanism of triangular principle is proposed in the paper. We con-duct the theoretical calculation of the amplification mechanism of the triangular principle, and conduct some static and dy-namic analysis with the method of finite element analysis, and we obtain stress analysis cloud and modal analysis cloud of the amplification mechanism of the triangular principle, which verifies the rationality of the design.
