Abstract

fetched live from OpenAlex

This article addresses the exact solution of free vibration of a beam with a concentrated mass within its intervals when the beam is subjected to axial loadings. This problem is frequently encountered in the design and modeling of resonant micro-sensors, where an exact model is required to calibrate the frequency output with a physical measurand. The significance of this approach is its ability to determine the exact mode shapes of vibration, which are necessary in the study of the time-domain response of sensors and determination of stability regions. The effects of the concentrated mass ratio, its location on the beam, and the applied axial force on the natural frequencies and the mode shapes of the resonant beam were studied in detail. The results of this study reveal how the mass ratio and location can change the sensitivity of the sensor to the input axial force. As an application of the presented approach, the modeling of a fabricated micro-electro-mechanical system (MEMS) has been discussed.

Teacher imitation

Not 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.
