- Additional information
- This work was stimulated by the need to understand and avoid fatigue failure in turbocharger compressor wheels that have been machined from solid using 5-axis machine tools. The stress concentrating effect of machining cusps has not previously been presented. 100 numerical models were analysed to cover a broad range of cusp sizes. Consistent trends in stress concentration factor were shown throughout. The work has continued with a Knowledge Transfer Partnership (KTP101163) with BorgWarner (C.Ellis: cellis@borgwarner.com) to incorporate the findings into the wheel design methodology. This will allow wheels to be manufactured more economically and with greater durability.
