Ensuring reliability with durability test benches - for durable and robust products
In product development, durability testing is a key component in ensuring quality, safety and reliability in the long term. Durability test benches make it possible to test products for their resilience and durability under realistic conditions. This allows potential weak points and failure risks to be identified and rectified at an early stage - before a product goes into series production or reaches the customer. This is not only crucial for compliance with quality standards, but also for your customers' confidence in your products.
What advantages does the solution for a durability test bench with Delphin offer you?
- Higher product quality: Realistic long-term tests allow weak points and signs of wear to be identified at an early stage and targeted improvements to be made.
- Minimized default risk: Endurance tests help to eliminate potential sources of error before market launch - this reduces complaints and recall costs.
- More efficient development: Automated test and control functions shorten development times and reduce your product validation costs.
- Maximum data security: 16 GB internal device memory with automatic archiving to PC or server reliably protects your test data.
- Operational safety even in the event of a fault: The systems restart automatically after a power failure and guarantee uninterrupted data recording.
- Fast response to faults: Automatic notifications by e-mail or switching output enable immediate fault analysis.
- Flexible test environments: Several test benches can be operated independently of each other - ideal for parallel service life tests of a wide variety of products.
- Convenient data evaluation: ProfiSignal allows you to analyze and document current and historical measurement data directly from your workstation.
The service life test is used to test a product in long-term operation and to qualify it for a defined service life. Typical areas of application are
- Environmental simulation of fan systems in motor vehicles
- Endurance test stands for oven doors
- Lifetime testing of window regulators
- Cooktop and hotplate testing
- Service life testing of fan motors
- Measuring the long-term stability of solar modules
Practical example of a service life test
Autonomous service life testing of fan and cooling systems at an automotive supplier
A leading automotive supplier specializing in the development, testing and series production of fan and cooling systems relies on comprehensive endurance tests under realistic conditions to ensure product quality. In order to prove the required service life of its components, the company carries out demanding endurance tests in which the test specimens are subjected to several thousand hours of stress.
The test specimens - including fan modules and cooling units - are installed in over 70 climate chambers operated in parallel. Typical daily and annual cycles are realistically simulated in these chambers, including temperature changes, humidity fluctuations and other environmental conditions. The tests are controlled and monitored entirely via the ProfiMessage devicee that work autonomously and do not require a permanent connection to a PC. In the event of a fault, an automatic alarm is sent by text message so that rapid intervention is possible at any time.
Particular attention is paid to the efficiency and reliability of test bench automation: the ProfiMessage systems not only continuously record data, but also generate and maintain the required setpoint profiles - for temperature, voltage or speed, for example. This ensures that all test conditions are precisely adhered to and documented.
The data collected during the endurance run (typically 2,000 to 3,000 hours) is transferred to a central server in real time and automatically archived there. Despite the enormous amounts of data, the software enables ProfiSignal a fast and comprehensive evaluation of the entire test period. Individual outliers or irregularities can be identified and analyzed immediately, ensuring complete traceability and quality assurance.
With this highly automated and scalable solution, the automotive supplier can realistically verify the service life of its products, increase process reliability and at the same time significantly reduce time and personnel costs in test operations.
