Engine test stands play a central role in the development and optimization of engines
Engine test stands are crucial for the development and testing of engines in the automotive industry. It is important that the test stand enables precise and reproducible measurements. This includes accurate recording of power, torque, emissions and other relevant parameters. In addition, the test stands must be safe and comply with the applicable regulations in order to avoid accidents. Calibration and regular maintenance of the test stands are also of great importance to ensure accurate results.
Motor test stands are required in the development phase as well as in series testing and endurance testing. If possible, measurements during development are carried out fully automatically and examine the test specimen with regard to electrical and mechanical properties as well as temperature behavior and overload operation. From testing the smallest motor to large drives in the MW range, the boundary conditions are often very different and must be adapted to the customer's specific requirements. The modular concept of the ProfiMessage devices and the compact Expert Key devices are available with a customized ProfiSignal application represents a cost-effective, automated complete solution.
Application highlights of the engine test stands
- Automated test sequence with convenient operation
- Control of DUT conditioning, power supply, FIs and switching matrices
- Temperatures, pressures, speed, electrical variables and torques synchronized in time
- Precise electrical measurement by connecting power meters
- Monitoring of limit values online during the test sequence
Practical example of an engine test stand
Complete testing of explosion-proof motors
In a type test bay, explosion-protected motors are tested at five independent test stations during development. A complete test sequence can consist of several partial tests, which are largely automated. The ProfiMessage devices record the data, control the test stands and are responsible for the complete test voltage management. The Delphin message hardware is used to control the relay matrices and frequency converters as well as the complete climate control of the power range. The devices exchange the required information with each other and independently of the PC. Redundancy in the control system guarantees reliable and smooth operation.
