T joints - Rough Notes Testing Plan
- Kyle Justin Lacson (Deactivated)
Background:
The T joint tested will be primarily be used to support the seat pan and supports. The seat pan and supports will be both made of a composite material. 6oz and divinycell foam 9.4mm thickness and 5 pounds per cubic foot.
Interface:
Bottom of the seat supports will be interfacing with floor panel. Image below is a small diagram of the floor panel where the seats will be placed.
The T joints will be placed beneath the seat pan as an extra support in addition to the seat supports (Triangle pieces connected to seat pan and floor). There will be 4 T joints connected to the seat pan and floor, 2 on either side of the seat supports. (The upper part of the T-joint: horizontal section will interface with the seat pan. In addition, more T joints will be oriented perpendicular to the seat supports with a total of 8 T-joints, 4 on either side of the seat support. (The brown sections indicate where the T joints will be placed.)
Loading Configuration:
The loading configuration will be shown on the image below, showing a distributed load on the top part of the T joint. T-joints made should undergo at least 5g’s of loading with at least 20kg applied.
Next Steps:
The testing plan for the new T joint loading scenarios would probably try to simulate a distributed load involving the necessary T-joints and using some sort of seat pan or metal construction to mimic the seat pan. In addition, weights of different masses and sizes could be added onto the metal construction instead of using the UTM as the machine is a concentrated load.
