Studying online

There are now 3 possible online modes for units:

Units with modes Online timetabled and Online flexible are available for any student to self-enrol and study online.

Units available in Online Restricted mode have been adapted for online study only for those students who require the unit to complete their studies and who are unable to attend campus due to COVID border closures. To be enrolled in a unit in Online Restricted mode, students should contact their Student Advising Office through askUWA and include which of the below criteria applies:

  • You are a student who is currently offshore and unable to enter Australia.
  • You are a student in Australia who is impacted by state or regional border closures.

MECH4426 Dynamics, Vibration and Sound

6 points
(see Timetable)
Semester 2UWA (Perth)Face to face
Semester 2OnlineOnline timetabled
The topics covered in this unit included motion and force in solid mechanics, lumped parameter mechanical elements, undamped/damped free vibration, forced vibrations with harmonic, periodic and transient excitations; basics of vibration isolation, vibration measurement instrumentation, vibration signal processing and its applications, passive noise and vibration control measures; two degree of freedom systems, multiple degree of freedom systems; vibration of systems with distributed parameters (strings, rods, beams and plates); wave motions in structures, air and water, modal, receptance and energy description of these mechanical vibration and waves.
Students are able to (1) explain the important characteristics of vibration behaviour; (2) develop vibration models using receptances, momentum and energy methods; (3) analyse the vibration behaviour of a range of physical systems using lumped and distributed parameter models; (4) explain the important characteristics of sound generation and transmission; (5) develop simple models to analyse sound generation and transmission; (6) carry out vibration and sound measurements in a laboratory setting; (7) locate and evaluate literature relevant to the unit content; (8) work effectively in a diverse team to achieve professional outcomes; and (9) communicate effectively through concise written technical reports, using discourse conventions relevant to the discipline.
Indicative assessments in this unit are as follows: (1) assignments; (2) laboratories; and (3) a final examination. Further information is available in the unit outline.

Supplementary assessment is only available in this unit in the case of a student who has obtained a mark of 45 to 49 and is currently enrolled in this unit, and it is the only remaining unit that the student must pass in order to complete their course.

  • The availability of units in Semester 1, 2, etc. was correct at the time of publication but may be subject to change.
  • All students are responsible for identifying when they need assistance to improve their academic learning, research, English language and numeracy skills; seeking out the services and resources available to help them; and applying what they learn. Students are encouraged to register for free online support through GETSmart; to help themselves to the extensive range of resources on UWA's STUDYSmarter website; and to participate in WRITESmart and (ma+hs)Smart drop-ins and workshops.
  • Unit readings, including any essential textbooks, are listed in the unit outline for each unit, one week prior the commencement of study. The unit outline will be available via the LMS and the UWA Handbook one week prior the commencement of study. Reading lists and essential textbooks are subject to change each semester. Information on essential textbooks will also be made available on the Essential Textbooks. This website is updated regularly in the lead up to semester so content may change. It is recommended that students purchase essential textbooks for convenience due to the frequency with which they will be required during the unit. A limited number of textbooks will be made available from the Library in print and will also be made available online wherever possible. Essential textbooks can be purchased from the commercial vendors to secure the best deal. The Student Guild can provide assistance on where to purchase books if required. Books can be purchased second hand at the Guild Secondhand bookshop (second floor, Guild Village), which is located on campus.
