Solar Car Racing 1987 - Solar auto dashing started with World Solar Challenge (WSC) crosswise over Australian Outback. 1990 - Solar auto hustling came to U.S. through General Motors supported Sunrayce. 2001 - Sunrayce was supplanted by the American Solar Challenge (ASC). July 2003 - UK took an interest in its first ASC race.

Slide 3

UK Solar Car Team Trials UK took an interest following 3 years of outline and development Competed in Qualifying Race After "scrutineering" for while, they understood they required devices for their auto ME 412 Team was doled out three basic parts that are required for achievement

ME 412 Areas of Design Hinge Wheel Alignment System Lifting Mechanism

Hinge Design By: Ryan Hoffman

Slide 6

Current Approach for Shell Removal Shell must be lifted off the auto by 3 or 4 colleagues The shell is then put on backings separate from the auto

Slide 7

Problems with Current Shell Removal Requires a few individuals to fulfill undertaking Requires moving or disengaging wiring and links going from auto to shell Risk of shell managing harm while in transport to the backings No flexibility of shell edge once set on stands

Slide 8

Design Requirements of Hinge Must keep up contact of the shell and auto Must permit access to the segments of the auto underneath the shell Allow driver to get to his seat Must permit the shell to be conformed to the ideal plot for the sun powered cluster to pick up the most measure of accessible daylight Must be lightweight since it will be a part of the auto yet solid to bolster the 200 lbs. weight of the shell

Slide 9

Hinge Design L-formed focus piece made of aluminum Angle iron with slide secured to shell bolsters on the shell to permit the shell to be lifted vertically then tilted to clear the lip of the shell Pins affixed in slide with thumbscrews to permit conformity of the shell edge regarding the sun

Slide 10

Analysis of Hinge When stacked with a 100 lbs. load at the area of the pin, the section builds up an anxiety of roughly 6 ksi.

Wheel Alignment By: Robert Krukoski

Slide 14

Wheel Alignment Requirements Be ready to have each of the four wheels adjusted Have the resilience inside two or three thousandths of an inch Need to be adjusted to the auto on the ground, and individual in drivers seat

Slide 15

Wheel Alignment Selection Process Four Major Designs Laser Guided Alignment Connecting Bars Independent 5 Point Alignment Slots on Ramp for Alignment

Slide 17

Design of Wheel Alignment Decided to run with Smaller Lift Independent Lifting best Design Aligning the wheels to the casing

Slide 18

Design of Wheel Alignment cont. Have sections circumventing the wheel Attach to Plate, Magnets Adjustable leg in front (Three Point Stand) Bubbles to adjust Wheels

Slide 19

Design of Wheel Alignment cont. What to use for real Calibration ? Adjusted Pins Micrometers Dial Indicators

Slide 22

Frame Design Selection Process Two Major Concepts Roll under auto outline Ramp Style – auto will roll onto outline We Decided on Roll under auto outline plan.

Slide 23

Lift Jack Requirements and Geometries Six Designs were Created Goals Design an edge that was basically solid (2000 lb limit) Total stature under 9 in. We likewise attempted to diminish weight

Frame Stress Analysis Description of physical framework

Slide 27

Lift: Wheel Selection The entire lift mechanical assembly and auto must be portable so as to make chipping away at the auto simple To do this, wheels must be intended to mount on the edge that will hold the heaviness of the auto and lift which is around 1500 lbs. The wheels must encourage movement in any course. As opposed to plan them starting with no outside help, we found a pre-outlined caster that would work for this application.

Slide 28

Lift: Wheel Specifications The caster has a 360 o swivel mount, with a discretionary brake Each caster has a 500 lbs. limit. One at every corner gives an aggregate limit of 2000 lbs. Minimal effort at $17.09 per wheel Phenolic Resin development for sturdiness

Slide 32

Lift: Air Bag Comparison Power Team air packs meet our necessities, particularly least tallness. The main disadvantage is the conspicuous high cost. In any case we trust that our financial plan can deal with the buy of two packs.

Slide 35

Design Review: Hinge Able to tilt sun based auto cover any wanted point sufficiently strong to hold the top and not fizzle under certain stacking conditions Simple to work

Slide 36

Design Review: Wheel Alignment Able to be adjusted at whatever time Simple to peruse, and work Able to get every one of the four wheels straight in respect to the casing of the auto

Slide 37

Design Review: Lift/Jack Slide under Car Able to lift auto and any extra load if necessary Air Bags have speedy reaction Total Weight of lift is roughly 155 lbs.

Slide 38

Final Thoughts Meet the necessities set by our guides Helps the execution of the UK Solar Car Team Given Helpful knowledge to our task Total Cost: Approximately $1300.00
