Hubs, Frame and Leaf Spring Testing

 Hubs are done. Bearings are not shown, but they have been installed. I only had three wheel studs, so the others are on order. The rotors also bolted right up with the original Z1000 bolts so no issues there. The ZX10 rotors do a nice job of filling out the wheels and should be more than sufficient for some nice nose wheelies. Plus, the Aprillia wheels look sweet in orange.

The frame is also done. We just went back with black for simplicity, although the orange looks good in electronic.The engine will go back in this week, so it will be nice to finally be in the "reassembly" stagee. All systems go for ride testing in June.

 Our friends at the University of Mississippi have completed some destructive tests on a few of our old Flex-Form springs. We had hoped to test these in an MTS rig, but leaf springs are a bit oddball so we ended up testing these on a hydraulic ram rig. Special thanks to James McPhail in the machine shop for setting it up; James also worked on the Monstrosity project, machining our hubs and center rocker, among other parts.
The guys from senior design also preformed some FEA wizardry, simulating various clamp designs to optimize for refuced stress concentrations. Changes in the design resulted in about 30% lower maximum stress concentration as well as increased maximum wheel travel. Thanks to Jeremy, Dan and Thomas for their excellent work on this project.

  1. I didn't see any dampening? is that not required for this type of spring?
