Problem
![Page 3: Bond Graph Assignment 19.169 Richard Mullen ME 114 Fall 2006.](https://reader036.fdocuments.in/reader036/viewer/2022082414/56649e795503460f94b79348/html5/thumbnails/3.jpg)
Procedure
• A bond graph was made in CAMPG of the system in the problem.
• While all of the values were constants, the source of effort caused by the unbalanced motor is a function of time– SE = m*e*wf*sin(wf*t)
• A simulink model was also created to compare values

Procedure
• All of the values were put into Matlab and displayed graphically

Simulink Model
![Page 7: Bond Graph Assignment 19.169 Richard Mullen ME 114 Fall 2006.](https://reader036.fdocuments.in/reader036/viewer/2022082414/56649e795503460f94b79348/html5/thumbnails/7.jpg)
Procedure
• All of the values were built into the model and the scopes display the results as a function of time.

Results
• The amplitude of the fluctuating force by analysis is 5.75 N, while the bond graph model gave about 5.8N.
• The amplitude of the displacement of the motor by analysis is 7.10x10-6m, while the bond graph model gave about the same answer of 7.10x10-6m.

Results
• The amplitude of the fluctuating force by analysis is 5.75 N, while the Simulink model settled down at between 5 and 6 N.
• The amplitude of the displacement of the motor by analysis is 7.10x10-6m, while the Simulink model gave about the same answer of 7.10x10-6m.

Conclusion
• The displacement matched up with the calculated value in the example, and the amplitude of the force was almost on for both the CampG and the Simulink models. There was a bit of noise on the force graph for an unknown reason, but it came out very similar. I can see that bond graphs and simulink models can be powerful tools to simulate many situations.
