Catalog Data

ME 5623: Mechanism Design, Credits 3. To give introduction to basic mechanisms, the course will

emphasize on mathematical modeling of planar mechanisms. The conceptual modeling practice will

start from basic concepts and lead to build complete theoretical models of mechanisms.

8. Chapter 8- CAM-Follower (4 Sessions)

Types of CAMS and follower motion

CAM functional considerations CAM design and manufacturing considerations

9. Chapter9Gear Trains (4 Sessions)

Fundamentals of gearing

Simple and compound gear trains

Transmissions and Differentials

10. Part 2 - Dynamics (6 Sessions)

Dynamics fundamentals

Dynamic force analysis Balancing

Computer Usage

Students have to learn the Matlab based Sim-mechanics tool box which will help them in designing

and evaluation of mechanism functioning. Another software is available with the text book on which

the students can work on to solve the problems.

Projects /Design Activities

The course involves a project activity during which students have to design and synthesize a

mechanism of their own choice. This will enhance their knowledge and design skills.

Evaluation Methods

1. Assignments 5%

2. Project 15%

3. Quizzes 15%

4. Midterm Exam 20%

5. Final Exams 45%

Student Learning Outcome

Students will learn about the design and synthesis of mechanisms, and machines and the underlying

concepts of kinematics. They will learn about links, Joints, kinematics chains, Degrees of freedom of

planar mechanisms. Special emphasis is given to enhance the student capability in building analytical

models of mechanisms. This will enable students to characterize the mechanisms before making or

bringing the mechanisms into realization.
