Wim van der Hoek Award nominees announced

14 November 2019

This year the jury, under the presidency of DSPE board member Jos Gunsing (MaromeTech), received three nominations, submitted by the graduation supervisor/professor of each student concerned. The nominations come from Fontys University of Applied Sciences in Eindhoven, TU Eindhoven and the University of Twente.

 

Wim van der Hoek Awards

 

The ceremony for the Wim van der Hoek Design Engineer Award 2019 will take place on Thursday, 14 November, 2019, at 16:15 on the Precision Fair in Veldhoven. Entrance is for free. You are welcome to join these award ceremony.

Candidates for 2019:

 


Paul van den Hoogenhof (TU/e)
Design of a thermally actuated objective lens focus system
“In his work on a lens focus system, Paul has shown competency in the mechanical design for nanometer-accurate positioning, as well as on a broader level in the full system design and integration by combining analytical modelling, simulations and experimental verification. Along with a design that more closely matches the desired operating range of the existing system, Paul has taken promising steps towards creating and controlling relatively fast thermal actuators that allow for very accurate and stable positioning. He has demonstrated good analytical skills and an ability to practically apply his knowledge to a variety of fields in an industrial environment.”
 

Sven Klein Avink (University of Twente)
Flexure mechanism with increased dynamic performance by overconstraining using viscoelastic material
“Sven has shown himself to be a multidisciplinary and enthusiastic student, who combined a good understanding of design principles and numerical analysis with an eagerness to explore the field of rubber technology. He studied a way of overcoming the limits that are imposed by the commonly used design principle of exact-constrained design. To that end, he developed a visco-elastic material and demonstrated in a self-designed set-up how it can be used to ‘overconstrain’ a flexure mechanism without the usual disadvantage of overconstraining, i.e. a sensitivity to misalignments (assembly tolerances). Sven’s work has the potential to lead to a new design principle in which a custom visco-elastic material is used to combine the best of both worlds, of exactly constrained and overconstrained design, respectively.”
 

Dominic Scheffers (Fontys University of Applied Sciences)
Hybrid guide – A revolution in translation for the ultra-high-vacuum industry
“In a very short time, Dominic has mastered designing with ceramics, an art that was previously rather unknown to him, and has realised a working prototype of a hybrid straight guide. For example, he demonstrated that his design works well and meets the requirement that the correct pre-tension can easily be applied. The hybrid straight guide also has a much lower rolling resistance than the existing ceramic straight guide and it is quieter. First, Dominic made a thorough analysis of the causes of rolling resistance in the current v-groove guide. He incorporated the results into a creative design that eliminates one of the most important sources of rolling resistance. The basic principle for his design of the guide was completely new and not known from the Koster and Soemers textbooks. He reported clearly and gave a comprehensible oral presentation, during which he could demonstrate the working prototype.”
