Sliding Load Apparatus

Sliding load and ice dynamics apparatus (SLIDE)

Purpose:

 

  1. Large scale ice–structure interactions; Test loads on full-scale ship structures and ice sheets.
  2. In-plane loads and lateral sliding impact; wet and dry sliding ice impacts.
  3. In-situ floating ice mechanics experiments.
Functions:
  1. Sliding Load Apparatus (SLA)
    • Apply sliding loads on the surface of the test specimen.
    • Use a modular moving indenter (ice, steel, concrete, etc.) and carriage on tracks.
  2. High Capacity Indentation Apparatus (HIA)
    • Moving wall will crush indenters into ice sheets (and ship structures).
Present concept design

Sliding load apparatus (SLA)

Capabilities
  1. Allows sliding and glancing impacts to structures:
    • Impacts by:
      • Ice, rock, wood, steel, concrete, etc.
    • Impacted structures:
      • Full-scale ship structures
      • Pipelines, offshore structures, etc.
    • Exists in a high-bay cold chamber (-25°-Ambient)
    • Vertical: 2 MN, 0.1 m/s, 1.5 m displacement
    • Horizontal:

        - 1.5MN; 0.1 m/s, 5.0 m displacement x-dirn
        - 1.0MN; 0.1 m/s, 1.5 m displacement y-dirn

  2. Can apply in-plane biaxial tension/compression.
Purpose

 

  1. Full-scale controlled laboratory impacts.
  2. Controlled Ice loads.
  3. Used to gain empirical knowledge and to calibrate numerical models.
