Course Objectives: This course expands on the mechanical engineering student’s background in kinematic synthesis and analysis by providing significant skills and experience in creating and modeling mechanisms. This course adds significant analytical skills in the mechanism synthesis process that will result in computational algorithms to automate the motion design process. This course also provides the tools necessary for kinematic and dynamic analysis of mechanisms and machines, and the skills necessary to consider the role of dynamics in the design of machines. This course will provide multiple exposures of computer analysis in the mechanism synthesis and design process.

Course Topics: T1. Analytical synthesis of mechanisms, exact and optimal synthesis methods (11 classes)
T2. Mechanism modeling (3 classes)
T3. Kinetostatic force analysis of mechanisms (12 classes)
T4. Engine dynamics, flywheel design, gyroscopic forces, (6 classes)
T5. Static and dynamic balancing of mechanisms (4 classes)
T6. Time response of mechanisms (3 classes)

Class/Lab Three 50-minute sessions/week,
Schedule: total equivalent 46 sessions/semester

Upon completion of this class, the student will:
Com 1. Be able to identify and distinguish basic and advanced mechanisms in the study and control of motion
Com 2. Be able to identify the design parameters inherent in basic mechanism types
Com 3. Understand the analytical techniques for basic linkage synthesis, including optimal synthesis.
Com 4. Be able to synthesize mechanisms analytically for a variety of tasks under a variety of constraints
Com 5. Gain experience in the kinematic synthesis process through implementation.
Com 6. Be able to evaluate the forces and torques in mechanisms and machines in operation
Com 7. Understand the fundamentals of engine dynamics and correlation to other machines
Com 8. Be able to perform static and dynamic balance of simple mechanism
Com 9. Gain experience and exposure in application of mechanisms and machines, and new fields of research in motion control

This course is required of Mechanical Engineering students taking the mechanical systems Area of Concentration (AOC). It provides advanced skills in the creating mechanisms for motion control, as well as skills in performing dynamic force analysis of machinery.

This course provides advanced analytical skills in synthesizing and analyzing kinematic systems. In addition, it introduces the role of dynamics in the analysis and design of machinery and provides the skills necessary to carry out these procedures. The course reinforces these skills by providing experience implementing the techniques in generating computer algorithms for synthesis and dynamic analysis of machines. It also provides significant experience in observing and implementing mechanisms in motion control systems. As a consequence, students who successfully complete this class will have the advanced skills and practical experience necessary in analyzing, designing, and selecting components for machinery.

Tests:
Tests will be given during regular class time. Every effort should be made to take the tests at the scheduled times. Make-up tests will only be given if prior arrangements have been made. Tests will be closed-book and notes, with a summary sheet (1-side, 8.5x11) allowed.

Quizzes / Homework:
Thursday will be “quiz or homework day.” Homework will be collected from the previous week’s assignment. Quizzes will be approximately 10 minutes in length and will be based directly on homework or lecture material from the previous week. Quizzes will be given at the beginning of class. The choice of quiz or homework will be announced on quiz/homework day.

Course Website:
A website for ME 464 will be part of the course. This site can be found in the ME department homepage, under courses on-line. Class announcements, homework solutions, review problems, quizzes, on-line help, and other features will be available through the “Dynamics of Machinery” site.

Help Session:
A help sessions will be scheduled as needed, particularly prior to exams. Topics will focus on homework and quiz questions and test prep but may include any subject of interest.

Office Hours:
Students requiring help are encouraged to contact the professor. The best times for help are after class, during help sessions, during office hours, or anytime on-line.

Insurance file:
Information on the insurance file policy is available at the class website.

Computer Program / Design Study
Several computer programs may be assigned. Examples may include creating a mechanism synthesis tool or performing a dynamic analysis of a mechanical system. These programs are to be written in Matlab and will include a graphical presentation of the results. The design study will involve applying class skills as well as the rest of your engineering background to investigate real-world applications. Suitable project choices will include designing aids for children with disabilities, investigating automation devices for local industry or modeling exercise equipment.

Graduate Credit:
Students taking this course for graduate credit will be expected to perform additional tasks as part of earning credit for this class. This will include extra homework problems, variations on the exams, and additional responsibilities in the special problems/projects.
