Number of students for this project: 1
Start: Flexible, early 2026 preferred
Your role
Target:
To build a dynamic calibration test rig for calibrating an Inline Rotary Torque Transducer (Control system).
Background:
Factories are using handheld pulse tools in assembly areas to boost productivity. These tools provide fast, reliable tightening with minimal reaction force and allow for one-handed use. Compared to impact wrenches, pulse tools offer greater accuracy, less noise, and lower vibration levels.
Currently, torque sensors are only calibrated using static methods. Traditionally, tightening occurs slowly (10–100 RPM) and can be considered as nearly static. With modern tools operating much faster and pulse tools delivering greater accuracy (a torque pulse lasts about 1 ms) there is growing interest in calibrating torque sensors dynamically, ideally up to 2000 Hz.
Mission:
Design a robust and flexible control system for the test rig. Conduct experiments, gather data, and do an in-depth analysis of the results.
Atlas Copco’s Industrial Technique business area provides industrial power tools and systems, industrial assembly solutions, quality assurance products, software and service through a global network. The business area innovates for sustainable productivity for customers in the automotive and general industries, maintenance and vehicle service.
