ME 372 Mechanical Design II (4 cr.)


Prerequisites: ME 262, ME 272, ME 274
Corequisites: NONE
Textbooks: Robert L. Norton, Design of Machinery: An Introduction to the Synthesis and Analysis of Mechanisms and Machines, Third Edition, McGraw-Hill Publishers .

Description: Kinematic and dynamic analysis of linkages and mechanical systems. Analytical and graphical approaches to analysis. Vector loop and relative velocity/acceleration solutions. Design and analysis of cams and gears. Static and dynamic balancing. Design for strength of various machine components. Reliability principles. Design documentation and communication. Laboratory experiments on mechanical design and strength.

Goals:
  1. To teach students velocity and acceleration analysis as an integral part in the process of design
  2. To teach students static and dynamic force analysis as an integral part in the process of design
  3. To teach students balancing of machines
  4. To teach students the design of mechanical components such as cams, gears, springs, screws, and clutches, which meet given design criteria, including strength requirements
  5. To teach students the design of mechanical systems such as cam-followers and gear train, which meet key performance requirements, including motion and dynamic performance
  6. To teach students state-of-the-art CAD/CAE technology (e.g., Pro/MECHANICA and I-DEAS) and show them how such powerful computer tools which can aid the problem-solving and design process
  7. To provide the students with hands-on experience in the design and analysis of mechanical systems through lab experiments
  8. To help the students develop effective/professional written and oral communication skills through report writing and oral presentation
