Test stand for transmission actuators

Extensive testing – automatic evaluation – fast results

• The device under test (DUT), an EC motor, undergoes a variety of tests
  - Characteristic curve measurement with acoustic testing
  - Back EMF
  - Torque ripple
  - Entire manual control
  - Testing with customer specific ECU instead of inbuilt controller
• The controller for the device under test is in the test stand and the test sequence integrated with parameterization and control via CAN
• Extensive parameter sets allow for flexible adaptation of the test sequences for the respective DUT
• Temperature controlled pauses ensure consistent test conditions
• Customized vibration-decoupled mechanics enable interference-suppressed structure-borne noise testing

Integrate testing and control with imc:

• Data acquisition with imc CRONOSflex 2000G with audio module in the test room
• Calculation and visualization of characteristics in real time
• Automated data storage in database
• Traceability of measurement data to test parameters
• Report generation with imc software solution imc FAMOS
• Test stand sequence control with imc measurement devices

2 of these test stands are being used by customers worldwide in Würzburg and Detroit. Transmission actuators are used in dual-clutch transmissions, transfer cases and for oil supply. Fast switching times and fuel-efficient driving style are possible through the use of electromechanical components in transmissions.
