Influence of Diagonal Groove Width on Stress Distribution and Deformation Behavior of Automotive Clutch Friction Discs
Bibliographic record
Abstract
The durability and structural integrity of clutch friction discs are critical to the reliability of automotive transmission systems, particularly under overload conditions.Among the primary geometric parameters influencing disc performance, the width of diagonal grooves plays a significant role in stress distribution and deformation behavior.In this study, the effect of groove width on the mechanical performance of a passenger vehicle clutch friction disc was systematically investigated.A three-dimensional model of the disc was constructed using Unigraphics NX, and numerical simulations were conducted via finite element analysis to evaluate stress, displacement, and safety factor by Ansys.Various groove widths were examined, with particular focus on a proposed configuration featuring a 3.5 mm wide diagonal groove.The simulation results indicated that this geometry yielded a maximum stress of 59.028 MPa, a total deformation of 0.027248 mm, and a minimum safety factor of 3.7932.These results demonstrate that the 3.5 mm groove width enables an effective balance between structural integrity and material efficiency, making it suitable for automotive applications where weight and manufacturing cost are constrained.The findings provide valuable insight for the structural optimization of clutch components and offer a reliable design reference for enhancing fatigue resistance under dynamic loading conditions.

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.
