Unformatted text preview: ME343-Dynamics of Machinery- Position and Displacement Analysis- Intro to Mechanism Design Sept. 28 nd , 2009 Midterm #1 Next week in class. (6 problems) Similar to the HW Closed Book & Notebook 1 page (8.5X 11) 1 sided note sheet Office Hours (This week only) Tuesday 11-12 / 4-5 No office hours on Thursday Midterm # 1 Kinematic Diagrams Vector addition / subtraction Mechanism displacement In line / off set crank slider mechanism 4 bar linkages Objectives of Position & Displacement Analysis Define position and displacement of a point. Graphically and analytically determine the position of all links in a mechanism as the driver links are displaced. Graphically and analytically determine the limiting positions of a mechanism. Graphically and analytically determine the position of all links for an entire cycle of mechanism motion. LIMITING POSITIONS The configuration of a mechanism that places one of follower links in an extreme location is called a limiting position. Two limiting positions are common. The displacement of the follower link from one limiting position to the other defines Stroke (Linear or Angular Displacement) of the follower. Limiting positions LIMITING POSITIONS: Graphical Analysis Solution Draw a Kinematic Diagram....
