Two graduates from the Osnabrück University of Applied Sciences, Julius Willmaring and Fynn Lammers, were awarded the first two places for their theses by the CLAAS Foundation of the agricultural machinery manufacturer CLAAS. Willmaring won first place with his work and will receive 600 euros each for the next twelve months. For his second place, Lammers receives 500 euros a month for one year.
The future scholarship holders received their award at the Claas headquarters in Harsewinkel. Both award winners dealt with topics from agricultural machine technology in their respective theses, but highlight different focal points.
First place for work on 3D printing in agricultural machinery manufacturing
Julius Willmaring has a bachelor’s degree in mechanical engineering and is currently studying production and development at the Osnabrück University of Applied Sciences. In his award-winning bachelor thesis, he analyzed to what extent additive metal manufacturing processes could advance lightweight construction at the agricultural machinery manufacturer Grimme now and in the future. “I have found that using selected additive manufacturing processes and topology optimization, i.e. a process for computer-aided structure optimization, significant weight savings can be achieved for two components,” explains Willmaring. However, the economic and functional analysis showed that the additive manufacturing of the components would currently still entail considerable additional costs. For this reason, industrial series production of these parts using additive processes does not currently appear economical. Today, 3D printing is primarily used where geometrically complex components have to be produced in small numbers. This will look very different in a few years because of the rapid development of manufacturing methods.
Prof. Dr. Viktor Prediger, Professor of Technical Mechanics and Machine Dynamics at the Osnabrück University of Applied Sciences, supervised Willmaring’s bachelor thesis: “The work is also so good because it not only reflects the status quo, but also shows that the technical development of 3- D-metal manufacturing processes will continue dynamically. It can therefore be safely assumed that these processes will gain significantly in importance for agricultural machinery construction in the future. “
Lammers analyzes new methods of chemical crop protection
Fynn Lammers has successfully completed a Bachelor’s degree in industrial engineering for agricultural and horticultural business with a specialization in agricultural engineering. He is currently studying “Applied Livestock and Plant Sciences” with a specialization in plant cultivation and agricultural engineering as well as “Precision Farming” at Harper Adams University. In his work, Lammers examined new methods of chemical crop protection in order to make it more sustainable. One solution is a site-specific application of chemical pesticides. This promises to increase sustainability through more efficient use. “In my work, I evaluated and validated a prototype from a monetary point of view on the basis of practical and theoretical assignments. For this purpose, I accompanied the practical assignments of two different companies and interviewed a total of seven different companies across Germany about potential applications in order to compare the cost structures of a conventional application and a site-specific application, “Lammers explains the procedure. Its results showed that costs could be saved on all farms. However, given the increased investment costs, these would not be worthwhile for everyone. This can be explained with the different structures, cultures and views of the developed prototype and its possible uses of the respective companies.
Prof. Hubert Korte, professor of agricultural engineering at the Osnabrück University of Applied Sciences, supervised this bachelor thesis and has already supervised students who have benefited from a CLAAS scholarship in the past. He emphasizes the cooperation with the CLAAS Foundation: “On the one hand, there is great appreciation that the students receive with the scholarship. On the other hand, it gives the students the opportunity to make important contacts for their later career entry. “
To the background:
The CLAAS Foundation was established in 1999 and has been awarding the Helmut Claas scholarship, bonus prizes and international prizes every year since then. This year’s winners from Germany, Hungary, Great Britain, the Netherlands, Russia, Romania, Slovakia and Poland received a total of over € 40,000 in prize money from the foundation.
