Introduction and Background - JJ

The purpose of this project was to apply the principles of machine kinematics and dynamics learned throughout the course. Application of kinematics fundamentals, position analysis, velocity analysis, and acceleration analysis was used to design, validate, and construct a physical prototype. For this project, I chose the six-bar window mechanism as illustrated below in Figure 1. 

Figure 1 

The six-bar window mechanism consists of a total of six different links. The illustration below shows the convention used throughout the remainder of the report. It lists the different notations for each link (Figure 2). 

Figure 2

Link 1 is the ground link or reference link for the assembly. Link 2 is the input crank for the entire assembly, the input torque will be applied at this link. Link 3 is the link that has a pin joint, pin in slot, and a slider attached to it. Link 4 is the slider block that is attached to Link 3. Link 5 is the pin in slot that is located in Link 3. Finally, Link 6 is the output crank of the entire assembly.
