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!
PO163: Reduction of crosstalk effects in multi-component force and torque transducers for wind turbine test benches via geometrical design optimisation
Lukas Schmitz, Research Assistant, Center for Wind Power Drives
Abstract
Wind turbines (WT) are one of the most important pillars of a climate-neutral energy supply. In order to promote the expansion of wind energy, it is essential to optimise the availability and reliability of WTs. WT system test benches enable the investigation of the behaviour of the entire drivetrain and control system under controlled and reproducible operating conditions. Throughout the testing process, the loads actually occurring on the drivetrain components can be measured. The data obtained from these measurements is then fed back into the design process to optimise the drivetrain regarding robustness. This ultimately results in improved availability and reliability. Torque is typically measured using a torque transducer near the prime mover. The non-torque loads are often calculated indirectly from the pressures of the hydraulic cylinders in the LAS. The separate and indirect measurement leads to inaccuracies. Direct measurement at the hub, using a multi-component force and torque transducer (MCFMT), can improve the measurement accuracy. However, measuring at the same position causes the individual measurements of the six load components to influence and distort each other leading to inaccuracies, known as crosstalk effects. The objective of this paper is an optimization method for reducing the crosstalk effects of an MCFMT for a WT system test bench via geometrical design changes. The method focuses on systematically identifying the optimal geometrical design parameters of the MCFMT, which will minimise crosstalk effects while accurately measuring the hub loads of a WT drivetrain. Several design variants are created and analysed regarding their crosstalk effects using finite element simulation models. Finally, a mathematical optimisation of the geometrical design parameters is conducted, resulting in the optimal geometry of the MCFMT. Torque and bending moment can be measured particularly accurately. However, adapting the geometry to measure thrust and shear forces proved to be a greater challenge.
