Paper Description

Edit Paper Description Content

Following topics are included in this paper:

Two degree of freedom system, equations of motion, eigenvalue problem, vibration isolation, shock isolation, vibration measurement and dynamics test, modal analysis.

All lectures will be on line. Students are given the opportunity to either join the lectures/tutorials/labs or work at home. Coming to the university or working at home is however, the student’s decision.

Due to COVID-19, there are ongoing changes to the timetable. Moodle Announcements will be used to inform of any timetable changes.

The learning outcomes for this paper are linked to Washington Accord graduate attributes WA1-WA11. Explanation of the graduate attributes canbe found at: https://www.ieagreements.org

Paper Structure

Edit Paper Structure Content

This paper is taught with face to face session and on-line lectures on mechanics of vibration.

Lectures, tutorials and lab sessions are scheduled for those who want to return to face-to-face learning. The activities will be recorded and will be uploaded onto Moodle for those who opt for working at home.

Solidworks and MS excel are two major software for the lab sessions. Students should have access to these software (links will be available). Similar to the tutorials, labs are scheduled for the students attending face-to-face session. Videos will be available on Moodle.

Note: due to the impact of COVID-19, the lectures content will be delivered through flipped learning and blended teaching (as per the UoW VC directive). This means that students need to read the lecture notes provided and view the recording available prior to any official lecture/tutorial/review.

Assessment

Edit Assessments Content

The assessment of this paper comprises one assignment, three lab reports and one final examination.

All tests and final examination are compulsory. Students must submit an "Extension of Deadline/Special Consideration form" if they cannot attend these tests. Otherwise, these tests will be considered as "Failing to complete" and results in an IC grade.

The tests and examination are open book and all questions should be attempted.

Samples of your work may be required as part of the Engineering NewZealand accreditation process for BE(Hons) degrees. Any samples taken willhave the student name and ID redacted. If you do not want samples of yourwork collected then please email the engineering administrator, Natalie Shaw (natalie.shaw@waikato.ac.nz), to opt out.
