Subject: FRAME DATA Posted by: PATRICK KWAN on December 19, 1999 at 04:55:37:

Message: I actually doing an experiment on vibration analysis on bicycle frame, it is about to measure the natural frequencies, vibration mode shapes and other characteristics, then applying damages on the frame and then do such experiments again to find another set of nat. freq. and mode shape, then use these data to compare with the theoretical assumption. I will connect the exciter and force transducer and accelerometer to the frame, and then through the spectrum analyser to analysis the vibration mode. By making such assumption, i must have to know the dynamics of the bicycle frame, stiffness, load distribution when external force is applied. Therefore i want to search informations about the mechanism of bicycle frame, and force dynamics and other data required to make my assumptions. Again thank you for your kindness! Patrick Kwan
