Senior Project #7: Longboard Test Apparatus, Derek Chan, Colin Harris, Nico Lee
Mechanical Engineering
The aim of this project is to create a machine that will test longboards made by Method Sports and Freebord. Through analysis and many iterations, Board Busters has assembled a design to fulfill the requirements set forth by these companies, who also sponsor the project. Through use of a four-bar, frame, and two spinning disks, the machine will accurately simulate riding conditions seen by a board in use by customers, allowing the sponsoring companies to improve designs and verify warranties.

This study presents the comparison of the theoretical and experimental results of the performance of an adjustable stiffness mechanism. In particular, the use of redundant actuation is emphasized in the design of a one degree-of-freedom Watt II mechanism capable of independently controlling the effective stiffness without a change in equilibrium position. This approach is in contrast to spring mechanism designs unable to actively control the spring rate independent of deflection, and with potential applications in various types of suspension and assembly systems. Results indicate that two direct drive brush-type direct current motors are required to drive the redundantly actuated mechanism …
