This invention belongs to the field of nuclear magnetic resonance technology and discloses a compact superconducting coil heat transfer structure and a liquid helium-free superconducting magnet. The compact superconducting coil heat transfer structure, applied to a liquid helium-free superconducting magnet, includes a tubular superconducting coil winding frame. A flattened superconducting coil assembly is wound around the outer surface of the superconducting coil winding frame via grooves. A heat transfer plate is provided on the outer side of the superconducting coil winding frame, and an end-face heat-conducting plate is provided at each end of the superconducting coil winding frame. Each end of the heat transfer plate is connected to the corresponding end-face heat-conducting plate, and a heat transfer metal plate is connected to both end-face heat-conducting plates.

This invention belongs to the field of bridge engineering technology and discloses a multi-stage variable friction energy dissipation bridge vibration damping device with constant pressure and anti-loosening function. It includes fixed friction plates, limiting rods, sliding friction plates, holes, a drive rod, a connecting rod, and a tension spring. Under the action of earthquakes, vehicles, and wind loads, when the main beam undergoes longitudinal and lateral displacement relative to the bridge tower, the drive rod causes displacement between the multi-layer sliding friction plates and the multi-layer fixed friction plates, generating frictional energy dissipation and suppressing vibration. The bridge vibration damping device of this invention has a simple structure, low cost, high friction force, constant force, low installation requirements, and good durability. The multi-layer fixed friction plates and sliding friction plates are made of non-uniform thickness plates, and the holes in different layers of sliding friction plates have different shapes, sizes, and positions to adapt to different amplitudes and energy dissipation requirements. The tension spring provides a persistent and constant pressure to the bridge vibration damping device, ensuring stable and reliable friction force and avoiding the defects of traditional bolt fastening methods, such as easy loosening and significant reduction in friction force.
