Material Model of Case-Hardened Steels for Turbo Gear Applications

Resultado final

Advanced Material Data Base for Material 2

After a successful completion of WP4, a extensive material data base for developing of the VHCF model for tooth root bending is available. The material data base includes two case-hardened steels. -Material properties of gear test specimen of material 2 -Tooth root strength of gear test specimen of material 2-Knowledge of failure characteristics (Fatigue limit 5 * 108)

VHCF model for calculation tooth root strength of spur gears

-State of the art analysis -VHCF model for case-hardened components

Final Design of High Power Recirculating Gear Test Rig

The output of WP1 will the concept of the recirculating gear test rig including the pre-design of the critical machine components as well as the completed design regarding the purchased machine components and the drawings for manufacturing. Furthermore, a detailed evaluation of the dynamic test rig behaviour will be an output of WP1. All results will be provided at the end of month 9 of the project. - Concept of high power recirculating test rig - Full design of test rig including machine components and drawings - Build up of an demonstrator test rig to prove the test rig concept - Evaluation of dynamic test rig behaviour
