Cover Story

Intelligent bearings make it possible to monitor the wear of highly stressed components during operation. Miba is developing innovative bearing sensors with their own power supply to permanently monitor the bearing condition in the fired engine and thus avoid maintenance costs and emissions.


New engine developments need to reflect rapidly changing environmental regulations, efficiency targets and, of course, reduced costs of development, validation and operation. Therefore, along with technical targets such as friction loss [1], cost targets for development, validation and time to market are all major considerations.

Due to the complexity of the cranktrain, the design is always a compromise, and not all critical design features can be simulated with the necessary accuracy. Operating conditions, load cases and production-related features are addressed in simulation, but the full picture still needs to be validated in engine test programs.

When it comes to prototype testing...
