Vertical Dynamic Structural Test Bench (VESPA) and Aggregate Services

Vertical Dynamic Structural Test Bench (VESPA) and Aggregate Services

Reliability and safety are decisive for vehicles which are getting more and more complex with ever more functions. In our facilities over the last 50 years, we have tested and qualified complete vehicles and their components in compliance with current standards and customer specifications.

Modern mobility concepts make the requirements for vehicle design ever more demanding. The Vertical Dynamic Structural Test Bench (VESPA) provides the testing technology for conventional as well as electric drives to meet these requirements. It combines fatigue strength, fatigue and vibration tests. In addition, it also permits noise and vibration analysis.

We provide our customers with a wide range of services, which can be individually customised:
