Dynamic Analysis of a Flexible Beam Undergoing Reciprocating Rotational Motion
Bibliographic record
Abstract
In this paper the dynamic characteristics of a flexible beam are determined experimentally and compared with those predicted by a simulation. A set of static experiments is first performed to validate the beam parameters and the experimental measurement approach. Next, the beam is set into motion as the rocker link of a planar four-bar crank-rocker linkage driven by a DC motor. Strain gauges, a potentiometer, and data acquisition system are employed to obtain measurements of the beam position history and corresponding strains during motion. From the signal analysis and data fit, the deflection and curvature of the flexible beam are determined. The simulation is carried out in ADAMS by creating a model with the same configuration and boundary conditions. The results of the experiment and simulation are closely matched. The long-term goal of this work is to develop practical means for continuous measurement of beam curvature and associated tip deflection and using that information to improve tip positioning control.

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.
