Six-Bar Linkage: Position - Velocity - and Acceleration Analysis

MIET2474 Mechanics of Machines

Answered

Task

For the six-bar linkage shown mechanism shown below, determine:

Q1 Determine all possible position of links and joints by graphical position analysis. Draw to scall all positions of joints for sixteen subsequent positions of link 2 and determine the limits of motion where appropriate. Identify and outline the paths of each moving joint.

Q2 Determine the linear and angular velocities by graphical velocity analysis for the given positions 2 = 60 of the mechanisms, as shown above. Draw to scale the velocity vector diagram encompassing all linear velocities to scale and present the results in a tabular form.

Q3 Determine all linear and angular accelerations by graphical acceleration analysis for the given 2 = 60 of the mechanism. Draw to scale the acceleration vector diagram encompassing all linear acceleration to scale and present the results in a tabular form.

Q4 Determine all instantaneous centers of velocity for the given mechanisms using Kennedy’s rule, and velocities of joints A, B,C and D using identified instantaneous centers. Draw all instantaneous centers to scale on a separate diagram of mechanisms.

The report should be prepared under the same sections as given above and should include all working including graphical, analytical and computer simulations. Include your disk/CD with Working Model solution.
