Advanced Mechanical Vibrations

Oklahoma State University MAE 5073 (#14404) Spring 2006

Course Objectives:

  • To formulate industrial dynamic problems in terms of vibrational models in order to identify the possibility of resonance, fatigue, or instability;
  • To recognize standard forms of vibrational models in order to draw on available analytical or computer solutions;
  • To solve problems with vibration, noise, and flutter in transportation, energy, and manufacturing equipment;
  • To specify instrumentation for vibration and noise testing;
  • To design machinery utilizing oscillation for transport or compaction.

    • Class Hours: 9:00 to 10:15 a.m. on Tues. & Thurs. in Engineering North 107.
    Spring Break: March 11 through 19, 2006.
    Final Examination: 8:00 to 9:50 a.m. on Tuesday, May 2, 2006; changes require the approval of the Provost.

    References: Every engineer should own one mathematical handbook with which (s)he is familiar. Some possible choices, sometimes displayed in the Student Union Bookstore opposite the main entrance, include:

    These books are also available from amazon.com.

    Other Resources: H.J. Pain, The Physics of Vibrations and Waves, 6th Edition, Wiley, Chichester, West Sussex PO19 8SQ, England, ©2005, ISBN 0-470-01295-1 (hardbound) & ISBN 0-470-01296-X (paperbound).

    Prerequisites: MAE 4063 Mechanical Vibrations, or equivalent.

    Course Content: Review of principles; analysis of non-linear vibrations, classical analysis of continuous systems — including webs, with reference to projects in the Web Handling Research Center — and numerical methods.

    Course Conduct: The course will be conducted in a traditional lecture format. Questions and class discussion relating to lectures, reading, and homework are encouraged. Civility, courtesy, and promptness are required.

    Examinations: There will be three "one-hour" tests and one "two-hour" final. No make-up tests will be given except in extreme circumstances, and then only upon arrangement prior to the scheduled exam.

  • All examinations will be closed-book and closed-notes, unless otherwise announced.
  • Academic Dishonesty: Looking at others' papers, exchanging information, or using forbidden resources during a test is considered cheating and will result in a grade reduction in the course---to "F" for a serious infraction.

    • Absences: This Syllabus is tentative. Each student is responsible for obtaining changes and additional information announced in class: homework assignments, test dates, schedule changes, modifications of the Syllabus, lecture notes, etc., and for being present at all examinations.

    Homework: Assignments will be due before the beginning of class on the due date; no late homework can be accepted. Graded homework will be returned in class or in the boxes in the Student Lounge, 202 EN. Solutions will be posted either in the second-floor hallway, opposite room 208 EN, or else on the instructor's website.

  • Academic Dishonesty: Handing in homework copied from others work, from files, or from stolen solutions manuals as one's own work is plagiarism, and will lead to a reduction in grade. Please note that learning through oral discussion is encouraged, but having others do your work for you is counterproductive. If you start solving a problem yourself, and then discuss it orally with others, you are learning. If you look at a file solution before you start solving the problem, you are approaching the unethical. Paraphrasing without giving a reference is still plagiarism.
  • You may use Scientific WorkPlace on the computers in the CEAT Labs open areas in Cordell South 286, 287, & 288; or you could purchase the inexpensive Scientific Notebook (http://www.mackichan.com/). Both include word processing which will enable you to explain your reasoning with verbal commentary; they also include TeX mathematical typesetting which will make your equations readable; and they run a Computer Algebra System (CAS) such as MuPAD in the background for manipulating matrices and algebra as you go. In addition, the Scientific WorkPlace LaTeX compiler includes Mark-up Language features for document organization and management.

    • Grading: There will be weekly assignments, three one-hour Tests and a Final Exam. They will count toward the grade as follows:

    Assignments 200 points
    3 Tests (100 points each) 300 points
    Final Examination 200 points

    for a possible 700 points. Letter grades will be based on the distribution of scores.

    Drop-and-Add Policy: Students should be in class on at 9:00 a.m. on Tuesday, Jan. 10, 2006, to participate in arranging the semester schedule. Substantive lectures begin on this very first day of class (Tuesday 1/10/2006); students adding the course late must make up the missed material through independent study. Until Tuesday, 1/17/2006, a student may drop the course with no record on his transcript. Other critical dates are listed on page 4 of the Class Schedule. Rules for grade assignment are given on pages 17 to 18 of the University Catalog. The grade of "I" will not be given to students preparing to repeat the course. A student may not drop a course in which a formal charge of academic dishonesty is pending.
