摘 要: Because of their remarkable performance, the use of compliant mechanisms has also been extended to the field of aerostatic bearings. This paper presents the design, modelling and experimental validation of a compliant mechanism used for a piezoelectric tool actuator to actively control an aerostatic thrust bearing. The proposed design procedure consists in a topological analysis of the mechanism, so as to define the kinematic functionality of the mechanism, a quasi-static analysis to tune its functional stiffness, and a modal analysis of the mechanism to identify its mode shapes. Experimental validation tests were performed to verify both the features of the compliant mechanism and the functionality of the system.

由于其出色的性能,柔性机构的应用也扩展到了气动轴承领域。本文介绍了用于压电工具执行器主动控制气动推力轴承的柔性机构的设计、建模及实验验证。所提出的方案包括对机构进行拓扑分析,以确定其运动功能; 进行准静态分析,以调节其功能刚度; 以及进行模态分析,以识别其模态形状。通过实验验证测试,进一步确认了柔性机构的特性与系统的功能性能。
