Measurement results
As specific optimization of skid geometry is only possible when load, location, time and position of the bob are known, all measurement results generated must be linked with the geometric and construction properties of the ice channel.
This was implemented by assigning the measurement results using an event map developed for the bob track. Figure 5 (see PDF file) shows a schematic diagram of the bob track in combination with the recorded axle load of a two-person bob.
The various events in the ice channel can be clearly recognized as sensor signals in the diagram. Because of the centripetal forces acting on the bob, the axle deflection and the sensor signal acquired increases quadratically with increasing speed and linearly with decreasing track radius.
At the last steep curve, the echo wall, the force acting on the pilot and team rises to five times their body weight. The bob is subject to the maximum force at this point.
