Swingarm Analysis

Ran the first stress analysis on rear swingarm – used a 3G vertical load as the loading, and used symmetry to model only half of the swingarm. Results look okay, nect step will be to analyze full swingarm with side and fore/aft loads as well.

First machined parts completed

Met with Pete this morning who had completed the spindles, a-arm brackets, and bellcranks. Parts look great, he is starting in next batch of drawings for frame and swingarm components.

8/25 Update

Spent the last month redesigning the frame and swingarm to use round tubing. After completing the initial design using rectangular aluminum tubing I felt the design would require too many small components to build. The round tubing also allows a better glue bond as the clearance between mating parts is more easily controlled than it would be in a rectangular design. The following pictures illustrate the final design – analysis of the main components is the next step.
