Endurance test bench for vehicle alternators
Fields of application
- Validation of the functionality and fatigue strength of four alternators subjected to certain loads and temperatures
- Definition of application-specific test cycles with predetermined load, torque and temperature collectives
- Direct comparative tests for multiple test items (operated in parallel) and recording of measured values for analyses
Test bench architecture and modules
- Mechatronic integration of different types of alternators
- Parallel operation of up to four different types of alternators
- Close-to-application mechanical fixtures for different types of alternators
- Interfaces: Analogue/digital or bus systems (e.g. LIN interface)
- Belt drive
- Close-to-application transmission and torques
- Adjustable, monitored belt tensions
- Dynamically configurable drive to simulate a vehicle's combustion engine
- Load simulation
- Dynamically configurable electronic loads of up to 7 kW (resistance or power mode)
- Energy recovery to reduce operating costs
- Temperature simulation
- Temperature range: -40 … +140°C
- Support for the parallel operation of two alternators at room temperature and variable temperature conditions
- Temperature chamber incl. lift and guide rails for easy mounting
- Metrology to record
- Current, voltage and torque outputs of the test items
- Temperatures of the chamber and the test items
- Automation
- Definition of application-specific test cycles with predetermined load, torque and temperature collectives
- Error control with individual limits for test items, belt drive, load simulation and the climatic chamber
