【摘要】：通过对一种新型柔顺铰链进行分析,设计一种基于对称型柔顺铰链的三自由度微定位平台。首先,采用ANSYS有限元方法,对一种新型柔顺铰链的输入力和输出位移间的关系进行分析。根据分析结果,通过优化设计得出一种对称型柔顺铰链。然后,设计一种基于该对称型柔顺铰链三自由度微定位平台,并对设计的微定位平台进行理论分析和有限元分析,得出其输入输出位移关系,而且理论分析和仿真分析结果基本吻合。同时,采用基于理论分析模型的仿真分析修正方法对微定位平台的传递传递函数矩阵进行修正,提高微定位平台的定位精度。此外,分析了该微定位平台的应力变形,确定了其所选材料的力学性能指标符合设计要求。结果表明,该微定位平台能够符合大多数精密领域的需求,在精密定位领域具有一定的应用前景。
[Abstract]:Based on the analysis of a new flexible hinge, a three degree of freedom micro positioning platform based on symmetric compliant hinge is designed. Firstly, the relationship between input force and output displacement of a new flexible hinge is analyzed by ANSYS finite element method. According to the analysis results, a symmetrical flexible hinge is obtained by optimizing design. Then, a three degree-of-freedom micro-positioning platform based on the symmetric compliant hinge is designed. The theoretical analysis and finite element analysis of the designed micro-positioning platform are carried out, and the input-output displacement relationship is obtained. And the theoretical analysis and simulation analysis results are basically consistent. At the same time, the transfer function matrix of the micro-positioning platform is modified by using the simulation analysis correction method based on the theoretical analysis model to improve the positioning accuracy of the micro-positioning platform. In addition, the stress and deformation of the micro-positioning platform are analyzed, and the mechanical properties of the selected materials are determined to meet the design requirements. The results show that the micro-positioning platform can meet the needs of most precision fields and has a certain application prospect in precision positioning field.
