Double pendulum dynamic impact test set-up for ice-grillage collision
Bibliographic record
Abstract
This paper details the development of a double pendulum dynamic impact test apparatus to study the behavior of collisions between ice and structural grillages, typical of those used in ship structures. Direct collisions between ice and ships involve high impact energy and can cause substantial damage to the ship structure. In order to apply this type of impact energy in a controlled and repeatable way, a double pendulum dynamic impact test frame has been developed. The frame consists of two pendulums: one to cany an ice sample and the other to carry a test grillage structure. The overall size of the apparatus is 4m x 5m x 8m. The live weight of each pendulum is approximately 3000 kg. In operation, the pendulums will be lifted and then released simultaneously to impact each other in a vertical position. The frame is instrumented to measure the impact force and deflection of the grillage. Copynght ©2012 ICETECH 12. All rights reserved.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
