WHAT IS AN ARBORLOO?

• Ecological outhouse

• Pit dug & supports in place

• Arborloo set up

• Arborloo removed &tree planted

• Combat deforestation in Haiti

5

• Wind resistance during Type I hurricanes

• Test collapsibility of arborloo

• Ensure safety in case of dislodgement

• Why is this a Senior Design project?

• Engineering skillset required to ensure all objectives are met– CFD, Force Analysis, Safety Engineering, Modeling, Cost Efficiency

• Set foundation for which all future arborloo designs can be tested off of

WHY IS THE STAND IMPORTANT?

6

The primary objective of this project is to design a scale model and a full-size test stand that will help determine the wind resistance of various arborloo designs. The scale model test stand should replicate the forces experienced by a Class I hurricane, and the results should be easily comparable to the lower speed, full-size results. Both test stands should allow for safe testing of various arborloo sizes, shapes, and materials.

PROJECT STATEMENT

7

• Create test rig & procedure for scale testing

• Simulate Type I hurricanes

• Measure wind speed, forces

• Create test procedure for full size testing

• Recommendations for future design of arborloos

PROJECT STATEMENT

Deliverables:

• Scale model and full-size test set-up and procedure

• Test Plan

• Means of comparing results from scale model and full-size testing

• Design drawings and Bill of Materials

• Assembly instructions

• Clearly documented test results

Objectives/Scope:

• Determine the appropriate fluid and scale needed to replicate a Class I hurricane

• Design a test stand than can be used for multiple different arborloo designs and configurations

• Demonstrate reliable and repeatable results

PROJECT SUMMARY

9

Assumptions & Constraints:

• Budget: $800

• Scale model must utilize existing fluid flow analysis equipment in KGCOE, while keeping current set-ups intact

• Test stand must protect surrounding people and infrastructure from flying debris

Expected Project Benefits:

• Arborloo designs can be tested to find the optimal design to be used in Haiti

• Test stand can be used by other senior design groups to evaluate their arborloo designs

PROJECT SUMMARY

10

• Software– Modeling arborloo designs with

CFD software

• Sensors– Using and collecting data from

sensors – Determining appropriate sensor

types

Issues & Risks:

• Project Understanding and Digesting By Team– Understanding of Class I

hurricanes– Determining critical locations to

measure moment and forces

• Available Resources– Obtaining Resources– Order Parts/Hardware– Lead Time

PROJECT SUMMARY

11

• Demonstrate reliability and repeatability

• Simulate wind speeds and forces of a Class 1 hurricane

• Protect users and bystanders while testing

• Protect other infrastructure and equipment from damage

• Allow for different shapes and materials to be tested and compared

• Allow for different weights and centers of gravity to be tested and compared

• Utilize existing equipment while keeping current set-ups intact

• Be creative in a manner for compact storage

• Provide easy to read instructions on how to assemble and use in a safe manner

• Is low cost (Budget <800)• Can be set up by 2 people• Can be set up and taken down

quickly• Long lifespan
