Variable-stroke self-adaptive adjustment quasi-zero stiffness device and parameter checking method

Abstract

A variable-stroke self-adaptive adjustment quasi-zero stiffness device includes an integrating sphere, a target, a collimator, a pointing measuring instrument, a disturbance source, an inertia simulation tooling, a quasi-zero stiffness suspension adjustment device and an optical air-bearing platform. The integrating sphere, the target and the collimator are coaxially mounted on the optical air-bearing platform in sequence. The pointing measuring instrument is connected and fixed with the inertia simulation tooling through a screw; three disturbance sources are mounted on the inertia simulation tooling to provide small disturbance and inertia for the pointing measuring instrument; the quasi-zero stiffness suspension adjustment device suspends the inertia simulation tooling to provide a free boundary environment; and the quasi-zero stiffness suspension adjustment device, the pointing measuring instrument, the disturbance source and the inertia simulation tooling form a set of two-pendulum system as a whole.
