Posters

Come meet the poster presenters to ask them questions and discuss their work

We would like to invite you to come and see the posters at our upcoming conference. The posters will showcase a diverse range of research topics, and will give delegates an opportunity to engage with the authors and learn more about their work. Whether you are a seasoned researcher or simply curious about the latest developments in your field, we believe that the posters will offer something of interest to everyone. So please join us at the conference and take advantage of this opportunity to learn and engage with your peers in industry and the academic community.

On 9 April at 17:15, we’ll also hold the main poster session and distinguish the 7 best posters of this year’s edition with our traditional Poster Awards Ceremony. Join us at the poster area to cheer and meet the laureates, and enjoy some drinks with all poster presenters!

We look forward to seeing you there!

PO152: Wind Turbine Main Bearing Unit Case Study - Comparisonof the Power Density, Manufacturing Costs and CarbonFootprints of a cast and an AHD steel hollow forged rotorshaft

Christian Hollas, Research scientist, Center for Wind Power Drives

Abstract

The Paper presents a wind turbine (WT) main bearing unit (MBU) case study, comparing the power density, manufacturing costs and carbon footprints of a cast and air hardening ductile (AHD) steel hollow forged rotor shaft. Based on a 2.3 MW low wind speed WT, MBUs comprising cast/hollow forged rotor shafts, main bearings and bearing housings are predesigned for highest power density. Furthermore, the manufacturing costs and carbon footprints for each component are calculated using estimation formulas. Early results show, that the MBU with the hollow forged main shaft reaches higher power densities than the cast variant. Due to the larger surcharges for hollow forging, the material required is higher and therefore the manufacturing costs of the hollow forging variant is more expensive.
