MECH4426 Dynamics, Vibration and Sound
- 6 points
Availability Location Mode Semester 1 UWA (Perth) Face to face
- 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.
- 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.
