Short Design Project 1:

40 Page 0r 10000 Word Limit

Due February 28th at 2:30pm

15% of your final grade

 

Design Project 2: to be done in groups of 4-5 students. Design a crank shaft made from steel, aluminum alloy, or titanium alloy to transmit a torque amplitude of 500Nm with a mean torque of 250Nm. The input has a square cross section and the output consists of a 15cm long crank arm with a circular cross section. Support bearings are 15cm apart and are located on one side of the crank. Your design must function at least 500000 times without failing and must be as light as possible and reasonably priced. Account for the failure modes such as yielding, fracture, and fatigue in your design and be sure to state any and all assumptions.

 

Note: peer evaluations MAY be used if deemed necessary by individual teams to shift grades for Project 1 on an individual team basis and would therefore be due with the project submittal. Use the summary sheet to record the scores you have given your team mates based on their performances which are assessed via the worksheet. Should any score fall below 75, you must attach peer eval worksheets for all team members to the peer eval summary sheet.

Long Design Project 2:

80 Page or 20000 Word Limit

Due April 6th at 2:30pm via email, include MECH3652 in the subject line

35% of your final grade

No drafts

 

In different groups of 4-5 students, design a suitable power transmission system for the following scenario. You must design the corresponding belt drive, chain drive, and gear drive and determine which option is the best and you may define a suitable application to frame your decision process. For the best drive option, you are also asked to design the output shaft including: material, dimensions, spline, keys, retaining rings, bearings, etc.

 

Input power = 1.25hp

input speed = 5000rpm

output speed = 500rpm

life = 50hours

output shaft power delivered via a spline connection

output shaft dimension = 15cm, from bearing centre to bearing centre with the gear, sheave, or sprocket located between the two bearings and the spline connection located outside of the two bearings.

Note: peer evaluations WILL be used to shift grades for Project 2 and are due with final project submittal. Use the summary sheet to record the scores you have given your team mates based on their performances which are assessed via the worksheet. Should any score fall below 75, you must attach peer eval worksheets for all team members to the peer eval summary sheet.
