Pneumatic Zero-Compliance Mechanism Using Negative Stiffness
This paper investigates the applicability of pneumatic actuator to zerocompliance mechanism for vibration isolation. A control method of realizing prescribed negative stiffness by a pneumatic actuator is shown. Its efficacy is verified in a fabricated single-axis apparatus. It was also demonstrated that the equalization of the amplitude of negative and positive stiffness enables the system to have zero-compliance to direct disturbance.
