Bidirectional Fluid-Structure Coupling Simulation Analysis of the Tank Body of A Liquid Tanker under Emergency Braking and Sharp Turning Conditions
Bibliographic record
Abstract
Based on the specific structural dimensions of a liquid tanker's tank body, a simplified 3D model of the tank body is constructed. Utilizing the Ansys simulation platform, a bidirectional fluid-structure coupling simulation environment is established. The working condition loads under sudden braking and sharp turns of the liquid tanker are designed, and finite element simulation analysis models under different filling ratios are constructed. By comparing the simulation results, the impact of the liquid inside the tank on the tank body and its patterns under different filling ratios are obtained. The simulation analysis results indicate that the greater the filling ratio of the tank body, the greater the impact stress on the tank body and the wave-proof plate, and the stress is proportional to the filling ratio. Both the stress of the tank body and the wave-proof plate are less than the allowable limit stress of 303 MPa, and both the tank body and the wave-proof plate meet the strength requirements.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
