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

A variable-stroke self-adaptive adjustment quasi-zero stiffness device, comprising:

• 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,
• wherein:
• the integrating sphere, the target and the collimator are coaxially mounted on the optical air-bearing platform in sequence;
• the integrating sphere provides a light source, the target provides point target information, and the collimator simulates infinity;
• the pointing measuring instrument is an object to be tested, the inertia simulation tooling is a hollow cubic structure, and 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 a 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.
