Experimental Investigation and Control of Magnetorheological Damper towards Smart Energy Absorption based Composite Structures for Crashworthiness
Bibliographic record
Abstract
This paper presents an extended experimental investigation and efficient control of magnetorheological (MR) damper towards smart energy absorption based composite structures for systems for crashworthiness. While the experimental evaluation of an existing MR damper based on the damping force was successful in our earlier work, the MR damper capability can be further examined with the wider range of velocities. Using two arms configuration, an experimental test rig is designed to enable the MR damper to be investigated throughout its full velocity range capability. A MR damper compatibility study to an existing composite tube was also conducted and showed promising quality to improve composite structures as systems for crashworthiness. A controller was then developed based on the MR damper investigation to provide automated variable control of induced current with a set crushing force and available data of composite tube crushing force. Numerical analysis on the proposed controller conveyed that MR damper was successfully controlled to provide consistent crushing force despite oscillation from the composite tube crushing force.

How this classification was reachedexpand
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.
