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
