Bolt Torque Calculator
Author: Sebastian Andreu
Course: 24679 - Designing and Deploying AI/ML Systems
This app calculates the torque required to tighten a bolt to a target preload using first-principles engineering formulas.
The interface allows users to input or select:
- Bolt diameter [mm]
- Target preload [N]
- Thread pitch [mm]
- Bolt material and lubrication (for estimating thread friction coefficient)
- Nut/under-head material and lubrication (for estimating friction under the head)
- Optional head diameter [mm]
The model outputs the required torque in Nm along with a natural language explanation of the result for non-experts.
How to Use
- Enter the bolt geometry and preload values.
- Select the bolt and nut/head materials and lubrication type.
- Optionally specify the head diameter; leave blank to use default (1.5×bolt diameter).
- Click Compute to see the torque and an easy-to-understand explanation.
Deployment Details
- Frameworks: Gradio
- Hosting: Hugging Face Spaces
- Model Loading: The LLM used for explanations is downloaded from the Hugging Face Hub on startup.
Requirements
Dependencies are listed in requirements.txt.
Includes: gradio, pandas, transformers
