AI Technical Summary
Existing magnetorheological shear thickening fluid dampers have low absolute storage modulus under extreme conditions, resulting in insufficient energy dissipation. Furthermore, their rate-sensitive characteristics cannot be fully utilized under power outages or low impact velocities, thus failing to provide adequate protection.
A variable-speed magnetorheological shear thickening damper is designed. By setting a pressure sensing unit and a shearing unit inside the cylinder, the impact velocity is increased by gear meshing. The magnetorheological shear thickening fluid and shear thickening adhesive are used as working media to give full play to their respective energy dissipation characteristics and enhance the energy dissipation effect of the damper.
The damper's energy dissipation and vibration reduction effect is improved under extreme conditions, ensuring effective protection even in the event of power failure or low-speed impact, preventing magnetic particle sedimentation, and enhancing the damper's sensitivity and energy dissipation capacity.
