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.
