Subsystem Build & Test
Table of Contents
Team Vision for Subsystem Level Build & Test PhaseWhat did we plan to do?
- Have all parts ordered and delivered
- Have fully assembled sandwich and frame (middle stage only)
- Point load testing on sandwich assembly
- Minor design optimizations
- Update risk management and problem tracking
What did we actually do?
- Partially Complete. Most parts ordered and delivered, Waiting on confirmation of pricing for Home Depot
- Incomplete. Hardboard, Plywood, and Adhesive are missing not yet ordered for Sandwich Panels. Stage Frame Members are cut to size, but still have to be milled, drilled, and welded.
- Partially Complete. Point load testing on sandwich assembly was conducted, and affirmed some earlier results, but is not as conclusive as desired without adhesive between materials. Testing will be redone when adhesive is acquired from Home Depot.
- Complete. Locking Mechanism was redesigned for ease of use and reliability. Finishing of Exposed sandwich panel faces was considered more thoughtfully. More effective solution for interface panels was established.
- Complete. Continually updated risk management and problem tracking
Design Optimizations & AdditionsLocking Mechanism The previous locking mechanism was fairly primitive in design, a block which acted as a hard stop that could be slid into place. With the intention of designing a simpler locking mechanism which was better integrated into the stage, we implemented a sliding pin protruding from the frame which will slide into the wooden posts which tie into the ground. The pin is intended to be disengaged before transformation and reengaged after transformation. There will be one pin for each section of stage.
Interface Panels There is a 0.5" nominal gap between sections of stage to prevent interference. The previous solution to spanning this gap was to place down removable, carpeted pieces of 1/4" plywood. However, this imposes a tripping hazard since the Americans with Disabilities Act of 1990 defines a trip hazard as any vertical change of over 1/4". A trip hazard on a performance stage is unacceptable. We consulted with Chris Beckley from Interior Design since we wanted the solution to not only be functional and safe, but also visually appealing. The solution he recommended was a thin metal T-bar which can be dropped into place between the sections of stage. The wall thickness is 0.05" which does not pose a trip hazard.
Stair Edging In an attempt to make the edges of the stage look nice, a stair edging will be used on the stage. This will conceal the end of the carpet and sandwich edge. At current, we are not set on a specific design or material.
