 MAMOTH PGB Project: Innovative Technologies for High Power Gearboxes

Explore the MAMOTH PGB project focused on improving high power gearbox systems through multi-scale modelling of carburised austenitic steels and predictive techniques.

Overview:

​

The MAMOTH PGB project focuses on the pressure quenching of carburised austenitic steels to achieve high strength and wear resistance through martensitic transformation. This process route is critical for enhancing the longevity of gearbox components. However, the high thermal and transformational strains induced during this process can lead to cracking in the material.

 

Multi-Scale Framework:

​

To address these challenges, a multi-scale framework has been developed to assess the impact of carbon content on phase transformation and the associated residual stresses throughout the broad thermal spectrum of the process.

 

Predictive Modelling:

​

The framework enables predictions of both trans-granular and intra-granular residual stresses, as well as dislocation dynamics, through crystal plasticity models. These insights are instrumental in paving the way for the development of dislocation density-based damage models aimed at void initiation.

 

By integrating these advanced modelling techniques, the MAMOTH PGB project seeks to enhance the performance and reliability of high power gearbox systems, ultimately contributing to improved operational efficiency and lifespan.
