Abstract
Mechanically complementary clamp configuration is a recent concept in piezoworm motor technology where both clamping sections can be driven simultaneously by same signal which reduces the actuation steps and drive electronics. Despite their opposite functionality, both normally clamp (NC) and normally unclamp (NU) clamps are designed based on same stiffness estimation so far. An improved stiffness model is proposed for normally clamp (NC) clamp section by considering the effects of the preloading, actuator displacement and flexure link length-thickness ratio in order to increase the buckling strength of the spring. It provides a more reliable prediction of the clamp behaviour both during its initial assembly, as well as under subsequently applied tensile loads in service. Finite element analysis is used to validate the proposed stiffness model. Experimental assessments are performed on the prototype to evaluate effect of the clamp stiffness on its displacement.

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 it
