Description
ACME Corporation currently has the material handler shown in the figure, which slides packages across a counter. The mechanism works with an electric motor that rotates at a constant speed of 10 rpm in an anticlockwise direction. Due to a change in processes, a simple 2.0 s stop is required at the extreme right position of the case drive, but maintaining the same constant 10 rpm engine speed. The manager, Mr. Wilie E. Coyote, asks his engineers to design a link mechanism with revolving joints that meets this objective. Apart from the previous consideration, it has these limitations:
The horizontal displacement of the final link of the manipulator (the one that drives the
boxes) must be the same as in the original design.
- The height from the floor to the boxes must be kept equal to the original design (0.6 m).
- The maximum space available for the new mechanism is 2.0 m to the right
measured from the original position of the motor.
- The maximum space available for the new mechanism is 1.0 m to the left
measured from the original position of the motor.
- The maximum height available for the mechanism is 2.0 m
5. Step-by-step detail of the design process of the new mechanism.
6. New mechanism with dimensions (dimensions).
7. Graph of the displacement versus time of the boxes for a complete cycle. Use
MotionView. New design
8. Graph of the speed versus time of the boxes for a complete cycle. Use
MotionView. New design.
9. Graph of the acceleration versus time of the boxes for a complete cycle. Use
MotionView. New design.
10. Engineering comments comparing both designs (original and new).
The document must be professionally presented. All graphics duly marked and numbered. The
axes of the graphs should show the corresponding units of measurement.
In addition, you must deliver:
MotionView file with final design. The MotionView file must be delivered with the 3D graphics
as real as possible (as the students have done in the tasks). Just for the final design.
