Semi-active control for a multi-dimensional vibration isolator with parallel mechanism
Bibliographic record
Abstract
In this paper, a vibration isolation system based on a parallel mechanism is proposed to isolate the multi-dimensional (MD) vibrations. The parallel mechanism, which is composed of three uniform [Formula: see text] (Prismatic pair with spring and damper elements–Universal joint–Universal joint) limbs and two platforms, has three translational degrees of freedom. First, the isolator is introduced and the dynamic model is achieved by a Newton–Euler method. Further, a sliding mode controller is designed to obtain the optimal damping forces as the control strategy is very essential to a vibration isolation system. At the same time, the time-domain hard constraints are considered in the controller design as the damping force can only be produced along the direction contrary to the relative velocities of the MR damper’s two ends. Simulations results demonstrate that the semi-active isolator using MR dampers has fine performance in reducing MD vibrations.

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.
