Component testing

Testing of individual components is an essential part of today’s development processes. This includes, among other things, customized component test beds.

In this process, the function of individual components such as transmissions, hybrid engines, generators, climate compressors, vibration dampers, cardan shafts and brakes is tested under a wide range of conditions.

The continuously increasing complexity is a great challenge, especially for manufacturers of sophisticated components.

Shortened development phases are countered by increasing requirements in terms of reliability, cost reduction and efficiency.

ERNST has developed a core competence in this area over many years with individual solutions of test bed mechanics. Customers benefit from our own design as well as in-house manufacturing and installation at ERNST.
