Computer-Aided-Engineering Project: (10%)
This project will be assigned May 7th. Each
person will create a computer tool to aid in the design of a machine element or
subsystem. Programs must be written in FORTRAN, and programs/routines you have
developed in previous classes can be built on and/or modified to complete this assignment. A users guide and report with a design example will be due at 5pm on May
No late reports will be accepted. A list of topics are given
below. You may also
submit your own topic - this must be sent for approval in writing via email
before class on by May 7th. A list of input and output
variables, and a flowchart of the program is due on May 12th.
Specific requirements of the program include:
- program must be interactive with the user
- program must recommend actual or nominal sizes (i.e. a 1/2 diameter shaft, not
a 0.489" shaft)
- reading from manufacturer's tables
accomplished by reading from data files
- program should be written in an
efficient manner to minimize run time (i.e. minimum program length).
- limitations, assumptions, and
warnings should be part of the output.
- output is verified with a design
example that includes hand calculations.
Potential topics include:
Roller bearing selection for a rotating shaft.
2. Shafts that supports a pinion
and gear drive.
3. Shafts that supports a sprocket
4. V-belt drive.
5. Roller chain drive.
6. Weld joint subject to shear,
torsion, and/or bending.
7. Fastener design for the lid of a
pressure vessel subject to dynamic loads.
8. Fastener design for a bolted
flange coupling on a rotating shaft.
9. Boundary lubricated bearing set
to support a rotating shaft.
10. Gear train
analysis/recommendations for simple, compound, and planetary drives.
