Dynamic measurements

The need for quality assured measurements under dynamic processes are large within many areas and businesses such as enery, health, manufacturing, materials and transportation. Some examples are measurements of forces in barrier tests, torque and ripple in electric engines or measurements in strength and durability testing.

Static calibration for dynamic measurements

Most measurements of mechanical processes take place under dynamic conditions. This works well as long as the instrument is faster than the process being measured. When the speed of the process increases the demands on the instrument also increases.

Basically all calibration of mechanical measuring systems take place under static or quasi-static conditions. This is partly due to the very low measurements uncertainties achievable.  However, primary methods for dynamic calibration are almost completely missing within force, torque and pressure areas.

This means that one cannot be sure what the measured values in fast mechanical processes really correspond to, and that results cannot be guaranteed to be comparable.

Project goals:

• Build knowledge for measurements of fast processes connected to the complete measurement system from sensor via signal processing to data collection units.
• Active participation in standardisation work and the creation of traceability chains for dynamic calibration of force, torque and pressure. Development of guidelines and frameworks both nationally and internationally.
• Give Sweden access to comparable and quality assured dynamic measurements at fast mechanical processes.
• The creation of a competence centre for dynamic measurements with national focus.
