Human Power Team Delft & Amsterdam - Human Power Team Delft

Design Presentation Human Power Team with Jan Bos

After a half year of research, design and testing, the Human Power Team Delft & Amsterdam will reveal the new design of the bicycle on Thursday 8th of March. You are invited! Not only the bicycle will be revealed but Jan Bos is also going to talk about his carrier as skater and what it means for him to be one of the selected cyclists. The presentation will start at 15:00 at the TU Delft Aula Congress Centre (Mekelweg 5,2628 CC Delft) , lecture room A.

A size measurement of the riders

It has been two months since the new riders of the Human Power team were announced. Now this of course leads to the question: will the riders fit in the bike or rather said does the bike have sufficient space for the riders. As a size measurement of the riders has been done on D-day the next step is to look how to implement this in the model of the bike. It takes a lot of time and effort to implement every rider in the model. Therefore, the largest rider is implemented in the 3D model. From the size measurement we can conclude that this is Sebastiaan Bowier. In order to implement Sebastiaan in the 3D model of our bike a 3D scanner of the Faculty of Industrial Design has been used. Because the most critical part is at the riders feet, the 3D scanner is applied on the feet of the rider. The output can be seen in Figure (3D scan).

Taking into consideration a sandwich structure with a wall thickness and a safety factor, one can check whether the rider fits in the bike or not. This can be seen in Figure (Rider in new bike).

This result was quite shocking and from this point one week of a great challenge started. The rider did not fit in the bike and there was only one week left for the final drawings of the molds, which had to be sent to NedCam. The challenge thus, was to develop the shape so that the rider does fit in the bike without losing the aerodynamic properties and to make drawings for the molds while taking the production process (that had been discussed with NedCam) into account in one week.

After one week of hard working a new shape has been developed and final drawings for the molds were sent to NedCam. The shape only shows 1% more aerodynamic drag than the shape which had been tested in the OJF. The drawings of the molds are discussed and verified with NedCam. The production of the molds has been started and in about 5 more weeks the production of our new shape will start!
