Mechanical Engineering
Dr. Porumamilla, Professor of Mechanical Engineering at Cal Poly, needs a way to demonstrate the concept of base excitation to the mechanical engineering students in the Mechanical Vibrations (ME 318) Lab. A mass-spring-damper model represented by a quarter-car suspension has been selected to represent this concept. A team of four students was assigned to design such a model as a senior design project. This document will explain the testing procedures, how were the results, and if they achieved our requirements. Furthermore, the document will explain how we assemble our product and manufacturing steps. Additionally, Critical Design Report (CDR) design changes …

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 …
