Testing    Interior - Robot testing

Robot testing

  • Testing under climatic conditions and at room temperature
  • Measurement of forces and torques
  • Robot-assisted endurance runs

Robot specifications

  • Kawasaki robots with a repeatability of ± 0.05 to 0.07mm
  • Forces up to 800N possible

Measurement of actuation forces

  • Single-axis and 6-axis force measurement
  • Force-controlled actuation to avoid overpressure / damage to the components
  • Recording force – path diagrams
  • Carrying out at room temperature and under climatic conditions

Testing    Interior - Endurance run

Endurance run

  • Endurance tests of all moving interior components
  • Pneumatic or robot-assisted component testing
  • Carrying out at room temperature and under climatic conditions

Testing    Interior - Shaker tests

Testing    Interior - Screw tests

Screw tests

  • Electronically controlled screwdriver whose screw parameters can be programmed via PC
  • Recording of all data during the screwing process
  • Torque range from 1 Nm to 50 Nm

Areas of application

Monitoring and checking of screw connections with regard to:

  • Screwing-in, over-tightening, further tightening and loosening torque
  • Settling behavior
  • Clamping forces

Testing    Interior - Component-specific tests

Component-specific tests

Testing    Interior - Measuring method

Scanning and photogrammetry

We perform optical, non-contact measurements of test pieces and component assemblies to analyze their interactions.

We work with the following systems:

  • Photogrammetry – TRITOP
    Object size: 0.1 m to 6 m
    Temperatures: -40°C to +100°C
  • Surface Scans – ATOS
    Object size: 0.05m – 3m.
    Temperatures: 0°C to +40°C

Color and gloss measurement

  • Using the spectro-guide 45 / 0 gloss
  • An average value is calculated by taking several measurements at different locations
  • The CIE L*a*b* system is used
  • With self-calibration
