Mechanical Engineering - MEEN 321

Dynamics of Machinery

• Apply fundamental concepts of kinematics, e.g., mobility, inversion, linkages, etc.
• Evaluate Grashof Condition for four-bar linkages
• Analyze position and displacement, velocity and acceleration of mechanisms using analytical and graphical approaches
• Using MathCad analyze an assigned mechanism over the full input range to determine position, velocity and acceleration of a critical point in the mechanism
• Synthesize linkages using graphical and analytical approaches                
• Apply fundamentals of cams, including S V A J functions
• Design cams based on type of motion, i.e., Critical Extreme Position and Critical Path Motion and on motion constraints, i.e., various rise-fall-dwell scenarios
• Apply fundamentals of gears (spur, helical, bevel and worm) and mechanism gear trains (simple, compound, reverted, epicyclic, etc.) to given motion specifications              
• Analyze and critique an existing mechanism and present results (oral and written) assessing its performance and how it can be improved                               
• Solve static and dynamic mechanism problems, including static and dynamic balancing
