Dynamics and vibrations analysis of punchbag

[satvinder]

hi i am a final year mechanical engineering student. For my final year project i have been given a project where i conduct experiments on a punchbag using sensors(accelerometers) and masses to strike the punchbag. Then using dynamics and vibrations analysis i should be able to calculate the force and speed of the punch as well as the location of the punch.

can somebody please explain this further to me as i am having trouble understanding what i have to do and exactly how to go about it.

any help will be greatly appreciated.

The first step for this project would be to design and build the necessary setup to conduct the experiments. This involves designing a mechanism to attach the sensors (accelerometers) to the punchbag, and also a system to apply the masses to strike the punchbag. The next step would be to program the system to record the output from the sensors when the punchbag is struck. Once you have the data from the experiments, you will need to analyze it using dynamic and vibrations analysis techniques to determine the force and speed of the punch, as well as the location of the punch. This will involve understanding the equations and algorithms used in dynamic and vibration analysis, as well as the principles of how the forces and speeds are calculated. You may need to use specialized software to perform the analysis, or develop your own code to do it. Finally, you will need to report your findings and draw conclusions based on the data obtained. This includes presenting the results of the analysis in graphical form and interpreting them to make conclusions about the force and speed of the punch as well as the location of the punch.
