Five nominations for the Wim van der Hoek Award 2022

The youngest generation of mechanical designers is still inspired by Wim van der Hoek’s construction principles. The nominations for the Wim van der Hoek Prize 2022 testify to that.

The jury, chaired by DSPE board member Jos Gunsing (MaromeTech), has received five nominations for students who have used existing or new construction principles in their graduation work in an appealing way. They come from Avans Hogeschool in Breda, Fontys Hogeschool Engineering in Eindhoven, KU Leuven (Belgium), TU Eindhoven and the University of Twente.

The prize is awarded for the seventeenth time on Thursday afternoon, November 17, in Den Bosch at the Precision Fair.

Candidates

Roy Kelder (University of Twente) – Active vibration isolation with an active stage

“Roy first got a university degree and had a technical side job. Thanks to his broad education and experience, he has been able to translate theoretical insights and analyzes into a functional and feasible design for an active vibration isolation system with very favorable dynamic properties. As one of the few students, he provided a design that our workshop technician could put to work immediately, without having to redesign it for manufacture. Roy has a hands-on mentality, which was evident, among other things, by arranging (‘crackling’) a free extension of the interface to our real-time hardware. With his energetic approach, he was able to get a lot done in his smooth exam period.”

Alexis Van Merris (KU Leuven) – Design of soft robotic EDM tool clamping for hard-to-reach zone machining

“Alexis has pushed the scientific boundaries of machine tools. He developed a revolutionary alternative to the rigid spark electrode that in Electro Discharge Machining (EDM) ensures that complex parts must be assembled from multiple parts, with all the associated disadvantages. Its actively bendable tool holder makes it possible to remove material from hard-to-reach areas via EDM. The application of soft robotics in machine tools is anything but trivial and can be entirely attributed to Alexis’ creativity. He conceived this concept and realized a prototype system. His work is of very high quality and combines excellent analytical skills with excellent practical insight.”

Julia Poelman (Avans University of Applied Sciences) – Project Rapid Stop: Design Report on the Development of a Collision Detection System for Handling Robots

“Julia carried out her graduation project very professionally and achieved a lot through her disarming attitude. In addition, she searches for the depth of content, investigates with a critical eye and keeps digging until everything is right. She has mastered new theory in a broad task and actively challenged it to find practical/experimental elaboration. She has delivered a very nice piece of work from a practical and theoretical point of view, technically very good with attention to detail. Because of the practical side, the validation is very strong and therefore the value of the end result.”

Jeroen Raijmann (Fontys University of Applied Sciences) – An integrated 3D-printed mounting system for optical elements that reduces light path alignment time in ARINNA

“Jeroen has made a monolithic adjustment mechanism for an interferometer, where it was important that there are no parasitic movements. He created a design to be printed in metal using two concepts of flexible mechanisms that he put in series. One mechanism is a linear guide with compensation for the parasitic motion due to shortening of the translation. The second mechanism is based on the so-called tetraspherical bending joint, where three rotations can be set around a point. Jeroen has worked in a very structured way and has completed a thorough literature study within flexible mechanisms and 3D metal printing. He is social, proactive and has a strong inner motivation.”

Dennis Struver (TU Eindhoven) – Design of a voice coil actuated active vibration isolator for cryogenic conditions

“Dennis has been researching a voice coil activated vibration isolation system for possible use in cryogenic conditions. This is one of the solutions to give the Einstein telescope for detecting gravitational waves a much improved sensitivity. Commercially available cryocoolers produce noise. For this Dennis made a very elegant design of a cryogenic active vibration isolator and largely realized it. He has shown that he is perfectly capable of coming up with an innovative mechanical and mechatronic design including control and analyzing it for critical aspects. He has great inventiveness and analytical skills and works very independently, although he also knows how to approach people to get relevant input.”

The Wim van der Hoek Award – also known as the Constructors’ Award – was instituted in 2006 on the occasion of the 80th birthday of Nestor in the construction principles Wim van der Hoek. The purpose of the award is to draw extra attention to and stimulate the profession of designing mechanical constructions. This prize is accompanied by a certificate, a trophy made by the Leiden Instrument Makers School and a sum of money sponsored by the EAISI Institute of Eindhoven University of Technology.

The Wim van der Hoek Prize is awarded annually for the best graduation thesis in the field of engineering in mechanical engineering at technical universities and colleges in the Netherlands and Belgium. Criteria for the assessment of the graduation reports are quality in the design, substantiation and innovation, as well as suitability for teaching construction principles.
