Final Report:
The Final Report consists of detailed documentation of the development of the project design to the final cradle, instructions on fabrication and manufacturing, an SOP, and additional information about the design.
Individual Component Analysis:
Each member of the team completed and Individual Component Analysis to learn more about the failure of the original hoisting assembly and what can be done to optimize the new design. A description of each report and the PDF and DOC to the full reports can be found here:
Individual Component Analysis - Hoisting Options - Nathan Han
With the functional requirements in mind, three different component options were proposed and investigated. These options included the original design of an M8 bolt into a tapped aluminum plate, an M8 bolt with the use of a Keensert (as suggested by the sponsor of the project Sean Casey), and a complete redesign utilizing a custom machined or purchased loop to pull from. An important aspect to note from the sponsor was that budget is not an issue and does not need to be a major concern for this investigation.
Individual Component Analysis - Safety Straps - Shannon Lo
The goal of this project is to develop a hoisting mechanism that safely lifts the PB2B receiver into the telescope to be mounted and secured. In the most recent attempt in lifting the receiver, the use of incorrect fasteners and the failure of the safety straps to protect the receiver resulted in it falling and hanging from the telescope, causing external and internal damages. Thus, this analysis is centralized on exploring various options and configurations of safety straps to ensure its functionality in protecting the receiver and minimize damage in the case any failure.
Individual Component Analysis - Mounting Fixture - Stephanie Cote
The Simons Array Polar Bear Hoist Assembly previously failed due to screws unfit for the mounting plate directly attached to the receiver. Due to the mounting structure failure, a new design and fabrication of a cradle that could not only support the receiver while being hoisted, but also decrease the dependency on the mounting plate as a whole as the threaded holes have been stripped from the failed operation. The mounting fixture is a necessary component to this cradle as it will replace the mounting plate as the connection between the cradle and the chain hoists.
Individual Component Analysis - Structural Tubing - Ray Nunez
An important component in constructing a structure is the material that is used and the configuration of the material. Besides the fundamental requirements, cost is the driving factor when choosing a material. In the building of a cradle for the Simons Array Project, consideration include: the type of raw material, the configuration of the material (i.e round, square, or rectangular tubing), and the cost.
