Mechanical Engineering
Mountain bike suspensions systems are set up and tuned based only on qualitative, ‘feeling’-based metrics. The MTB DAQ, sponsored by Dr. Joseph Mello with the Cal Poly Mechanical Engineering Department, is a data acquisition system we developed to improve suspension tuning with a data-driven approach. The system mounts to a bicycle frame and has sensors that measure vibration and travel speed to characterize the bike’s motion. While similar systems exist, they cost in the thousands of dollars range and are very specific to individual bike geometry. Our system was designed to be more affordable to the average rider as well …

Nathan Cooper is an 8-year old boy with Spinal Muscular Atrophy (SMA). SMA has affected Nathan’s muscle development and requires him to use the Standing Dani™ mobility device. The Standing Dani is a motorized standing wheelchair, or Wheelstand. Nathan controls and uses it to get around. Though the Standing Dani performs well for most functions, it has some distinct issues. The primary issue that this project addresses is its lack of suspension and the discomfort that Nathan feels as a result. After talking with our client, we developed several specifications generally related to geometry, safety, vehicle dynamics, and reliability. Many …

Pedaling And Braking Forces And Their Effect On Suspension Performance, Kathleen Kramer, Nik Goodell, Cesar Giron
Mechanical Engineering
The goal of this project is to produce a quantifiable relationship between pedaling and braking forces and suspension behavior. The test results will serve as a benchmark, against which other suspension designs can be compared in an objective, numerical manner. This report details the work completed towards determining this relationship and is primarily focused on design development of the data acquisition system and analysis of braking forces, pedaling forces and suspension response. A 2011 Specialized Stumpjumper FSR Expert Evo was used as the development platform. The system will be used to measure various rear suspension designs for comparison.
