F.R.I.T.S. is a force controlled test system based on an ABB robot. Its payload, velocity and measurement technique as well as its frequency range and its degrees of freedom, enable F.R.I.T.S. a range of endurance tests for vehicle components.

Due to the measurement technique, it is possible to induce loads, measure forces and stroke or to equalize differences to the reference values and finally log the complete data.

The innovative testing system and its special name have been developed by ACTS engineers. The symbiosis with ABB creates a fully comprehensive testing know-how for manufacturing companies, bundled in one contact.

The F.R.I.T.S. robot is not only a product, distributed by ACTS, it is also used in-house for endurance tests. So a new testing system has been created: from user to user.

Area of application

  • Force or position controlled test sequences 
  • Analysis and programming of entry and exit curves
  • Execution of endurance tests on vehicle components, e.g. seats
  • Execution of “intelligent“ tests, e.g. adjustment of forces due to unforeseen change 
  • Execution of tests for optimizing the comfort 
  • Benchmark possible with a variable number of seats
  • 3D measurement (accuracy: ± 1 mm)

Why F.R.I.T.S.?

  • Short set up time
  • Less Input for further tests
  • Continuous measurement data
  • Static load up to 3 kN
  • Dynamic oscillating tests (sinus) < 6 Hz
  • Force and torque characteristics definable (depends on device)
  • Modifiable sensor system according to the subject
  • Conformity to national and international standards (CE/UL–Declaration of conformity)
  • Verification of the functionality and comparability in intercomparisons
