X. (Small scale) guideway

Background

• ATN can revolutionize transportation (it will)

Description of the sub-team and objectives

• Design a model that can display full scale track to be understood by public

Design requirements and specifications

• Track should be modular
• Track should be able to accommodate up to ten vehicles

State of the Art/Literature Review

• Mostly suggestions from previous year teams

Description of Design

• Four-loop track design thought up
• Eight stations with support at each station
• Six straight way sections for two-loop
• 28 supports with 14 supports for each two-loop design
• last year’s design

i. 4 inch tall concrete base/12 inch diameter

ii. Post mount design is steel plate

iii. Four brackets

iv. Multiple bolts to secure the post

• Support post Design was simplified

i. Square steel tube that was slightly larger than one inch that protrudes through concrete base

ii. Support post falls right inside larger square tube

iii. Reduced size of concrete base to three inches in height and ten inch diameter

iv. Reduce weight from 40 pounds to 25-30 pounds

• Simplified post connector design simplified
• Design uses inch square steel tube that is an inch long that will act as a spacer that will separate post from guideway connector.
• Half diameter steel bolt with nut put at end to secure the steel tube in between post and connector

Fabrication

• Only enough time for two loop
• Formulated schedule of when and how parts would need to be fabricated
• Constantly referred back to main drawings
• Fabrication work separated into 4 different parts

i. Welding

1. Took small pieces from old track and welded them together to make longer new section → Used 100 amps to weld the straight sections together → Created 3 sections of straight track that were 88.65 inches long
2. Went on to welding the connectors to the bottom rails
3. Screwed on top rail

ii. Bending

1. Laid out drawings in E123 room
2. Top rails were found to be much easier to bend since thickness and width of piece was much smaller than bottom rails

iii. Supports

1. Built Concrete with help of CE junior Madrianne Medranoo

iv. Assembly

1. Labeled all sections (6 straight sections, 4 outer curve sections, 4 inner curve sections, 4 stations)

• Support connectors made to help connect supports posts to guideway

Product Analysis and Testing

• Tested one of bogies on track
• Some of the bends of the top rails were a little off
• Once everything was rebent, it was all right
• Some areas of track were sanded off to ensure a smooth transition to certain areas of the track

Finances

• Only a total of $48.78 was used from superway account

Results

• Old and New bogies were pushed around the track

Conclusions and Suggestions for Future Work

• Design specifications met
• Track is easily modular
• Support posts are easier to attach on and are much lighter to transport
• Communication with other teams extremely important
• Alot of money saved because of bending aluminum in shop
