, Situation description
You work for a consulting firm that provides solutions to machinery problems. A client has requested
for your assistance to solve some issues with a mechanism of their machine. The following is the email
you have received from the client.
Email from client
Hi,
As mentioned on the phone earlier, we need your assistance in troubleshooting a mechanism of our
machine. I have included some information regarding the mechanism and its issues in this email. The
following is a diagram of the mechanism.
A slider is constrained to move radially along the groove while the disc rotates about its own centre of
mass (fixed). This mechanism is however faulty and requires maintenance before it can operate
properly. The problems are:
1) The speed indicator of the rotating disc is not accurate and requires calibration.
2) The speed of the slider relative to the groove is unknown.
3) Due to problem (2), it is difficult to estimate the exact time to stop the mechanism before the
slider reaches the end of the groove (and collides with the wall of the groove).
To help with the investigation of the problems, we have mounted sophisticated motion sensors on the
slider. The motion sensors are capable of measuring (i) the position of the slider with respect to (w.r.t.)
the centre of the disc, (ii) the absolute velocity of the slider, and (iii) the absolute acceleration of the
slider.
Note that the slider can be treated as a particle and the measured distance from the centre of the disc
to the end of the groove is 900 mm. We have also mounted two cameras – Camera 1 on the stationary
fixed support and Camera 2 on the rotating disc (i.e., rotating with the disc), as we thought some video
recordings from the two cameras might be of interest for your analysis. Finally, I have attached a form
below and we would appreciate it if you can report the results of your analysis and your suggestions
using the form.
Look forward to hearing from you!
Regards,
Client
