Design Of An Internal Gear System For Bike Transmission Systems

Michelle Whiteside, M.S. University of Utah, May 2005

The existing prototype of the integrated gear selector works well for all but 2 out of 15 gear shifts. Whenever the chain has to be moved between the front chain rings, the rider needs to ease up on the pedals in order to allow the chain to shift (shifts that involve only the rear derailleur can occur under full load). The solution to this problem is an internal gear system based on a planetary gear box that can be shifted under full load as well.

 
   

Spherical Air Bearing Design

Yuchiang Lin, M.E. University of Utah, May 2005

This project is based on the assumptions of a linear, non-compressible flow to analytically predict the flow rate, load capacity, and stiffness of spherical air bearings. The project investigated the use FLUENT to model such bearings and compare the results with experimental data.

Density Evaluation

Eberhard Bamberg, University of Stuttgart, 1996

Dichteauswertung (32-bit Windows) is a tool used to analyze experimental data from cutting tests. The software reads in arrays of data generated from force sensors attached to the workpiece fixture and predicts the wear of the cutting edges.
