Design Of An Automatic Wood Trimming Machine, Van Ho, Nicholas Maskal, Andrew Rutland

Mechanical Engineering

This final design report, prepared for Sunrise Arts by the Cal Poly design team Mahogany Automation, details the year-long process in which the team of three engineering students designed and built an automated wooden -plank edge trimming machine that incorporates anti-jamming and continuous loading features. The team has examined current woodworking machines and features available on the industrial and commercial market, and used these as guides along with device requirements set by the project sponsor, Bruce Palmer. The focus has been on designing the simplest and most cost effective device that allows operators to make production runs of wooden slats …

Loaded Shift Tester Sram, Nick Cox, Sam Shaffer, Michael Polka

Mechanical Engineering

This report details the design, manufacturing, and testing of a loaded shift tester for the SRAM Bicycle Corporation. The machine is used to perform developmental and qualification tests on various bicycle drivetrain components. Using SolidWorks, the design team created a solid model of the machine on the computer, then ordered and manufactured the parts required to build it. The machine was tested to ensure that all the parts worked together, and was finally delivered to SRAM when it was deemed ready.

Exploration Station Kidshake Table, Jeremy Duhe, Philip Hopkins, Matt Ostiguy, Samantha Weiner

Mechanical Engineering

The KIDShake Table is an all mechanical earthquake shake table sponsored by the Exploration Station Children's Museum of Grover Beach. This interactive exhibit has two working mechanisms, a hand crank and pull rope, that provide two axis movement for knocking down block structures. This table was built and designed for a target age of 10 years.

Drape Forming Machine, Adam Johnson, Will Schlosser, Brian Miller

Mechanical Engineering

The goal of this project was to build a prototype machine that formed multiple sheets of debulked pre-preg OOA carbon fiber into a 2-foot long trapezoidal shape. The machine was required to do this process semi-automatically.

Bicycle Wheel Test Machine, Dylan Harper, Kevin Hom, Ross Williams

Mechanical Engineering

In recent years, the cycling industry has witnessed huge advancements in bicycle components and materials. The age old goals of speed and low weight are still present today, but the pursuit of these goals may be reducing the structural stability of various components integral to wheel performance, including the wheel hub bearings. These bearings are invaluable to bicycles but little is known about how the forces and loads applied to a bicycle affect the performance of these bearings. Broken axles and hubs are indicators of significant stresses within the hub, but little is known about how the resulting deformation affects …

Rapid Decompression Containment System, Evan Domingue, Michelle Rudney, Daniel Trees

Mechanical Engineering

Cal Poly students; Evan Domingue, Michelle Rudney and Daniel Trees; are working with General Atomics Aeronautical Systems, Inc. (GA, ASI) and engineer John Wilcox to complete a senior project. The senior project is focused on finding a solution to meet the requirement set forth in MIL-HDBK 1791 4.2.5.2 for rapid decompression which requires cargo items to be designed with pressure relief devices or to be configured for air shipment as to prevent any part from becoming a projectile in the event of catastrophic loss of aircraft cabin pressure. The goal of this project is to design a safe, cost-effective, and …

Rebounder Fatigue Test Machine, Caroline Reeves, Will Robertson, Ethan Flory

Mechanical Engineering

JumpSport, a company that designs and sells trampolines and trampoline accessories, has sponsored this senior project team to design, build, and test a trampoline fatigue test machine. The machine must simulate a person jumping on the trampoline to test the life of JumpSport’s fitness trampolines and kids’ trampolines. Partway through the design process, the objectives were altered and this senior project team was tasked with merging with another Cal Poly senior project group to create an all-inclusive test machine to accommodate both full-trampoline testing and individual bungee cord testing.

The final design is centered on a slider crank linkage driven …
