ME 372 Mechanical Design II
Outcomes: After completion of this course, the students should be able to:
1. Operate and explain the function of typical mechanical systems, such as cam-follower
systems and planetary gear trains [a4, b].
2.
Measure and explain the effect of design parameters on system dynamics and
performance, including the effect of cam profile on the dynamics of a
cam-follower system and the effect of unbalance on the performance of a rotor
[a4, k4].
3.
Calculate and experimentally measure the speed reduction and the efficiency of
planetary gear systems, and to observe the effect of design configuration on
the efficiency [a4, b].
4.
Measure the effect of design parameters
(i.e. material strength) and operating conditions (i.e. magnitude of cyclic
load) on the lifetime of machine elements subject to fatigue and explain the failure due to fatigue [a4, b].
5.
Determine failure due to creep by generating the
extension-time curve and extracting creep constants from experimental data and explain the creep phenomenon[a4, b].
6.
Observe the phenomenon of whirling and measure/extract
modal parameters at resonance in order to explain failure due to resonance (or excessive vibration) [a4, b].
7.
Work in teams to conduct experiments effectively and efficiently [g].
8.
Collect, process, and analyze data, and write lab reports to document
experimental work [g, b].
