Development test bench for electric actuators
Fields of application
- Function development, optimisation and validation for electric drive systems
- Analysis of drive functions in the HiL network (ECU and BLDC motors, for example, possibly with transmission)
- Identification properties and dynamics, also under specific climatic conditions
Test bench architecture and modules
- Load machine and modular load drive configurations for flexible operation
- with highly dynamic load machine (e.g. ±12 000 U/min, ±20 Nm with high power density)
- with/without flywheel mass, with freely rotating or clamped test item
- Electricity supply for test item
- Vehicle electrical system simulations (12/24/48V) for power as well as logic and energy recovery with dynamic bidirectional power supply units (up to ±450 A)
- Optional battery switch to connect a battery simulator
- Optional integrated supercaps to simulate storage in vehicle power supply systems
- Temperature or climatic simulation
- Temperature (-40 … +150°C) and humidity control (10...85% RH)
- Standard or customer-specific chambers, units and interfaces
- Metrology
- Torque and speed measuring technology with applicable measuring ranges and resolutions
- Measurement of current, voltage, temperature and acceleration
- Optional integration of electrical power meters
Automation and functions
- Manual and highly automated analysis of characteristics, efficiency or long-term stability
- Determination of harmonics, torques and step responses
- Automatic identification of transmission functions and test item parameters
- Database-oriented test sequencer for developing specific test programmes
- Flexible model integration and extension options for FIU functions
- Automatic report generation of test results with DIAdem
