Content 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.
Outcomes 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.
Assessment Typically this unit is assessed in the following ways: (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.
  • Books and other material wherever listed may be subject to change. Book lists relating to 'Preliminary reading', 'Recommended reading' and 'Textbooks' are, in most cases, available at the University Co-operative Bookshop (from early January) and appropriate administrative offices for students to consult. Where texts are listed in the unit description above, an asterisk (*) indicates that the book is available in paperback.
